NCERT Solutions for Class 10 Maths Chapter 3: Pair of Linear Equations in Two Variables - Exercise 3.2

Exercise No. 3.2 

1. Form the pair of linear equations in the following problems, and find their solutions graphically.

(i) $10$ students of Class $X$ took part in a Mathematics quiz. If the number of girls is $4$ more than the number of boys, find the number of boys and girls who took part in the quiz.

Ans: Given that $10$ students of Class $X$ took part in a Mathematics quiz.

We have to find the number of boys and girls who took part in the quiz.

Let the number of girls be $\text{x}$.

And, number of  boys be $\text{y}$.

Then we get

$x+y=10$ ……..(1)

Now, according to the question, number of girls is $4$ more than the number of boys.

Then we get

$x-y=4$ ……(2)

Now, the algebraic representation of equation (1) and (2) is

$x+y=10$

$\Rightarrow x=10-y$ 

The solution table for the above equation is 

Now, for eq. (2)

$x-y=4$

$\Rightarrow x=4+y$

The solution table for the above equation is 

Now, the graphical representation is

By observing the above graph we can say that the lines intersect each other at point $\left( 7,3 \right)$.

Therefore, $3$ boys and $7$ girls took part in the quiz.

(ii) $5$ pencils and $7$ pens together cost $Rs.\text{ 50}$, whereas $7$ pencils and $5$  pens together cost $Rs.\text{ 46}$. Find the cost of one pencil and that of one pen.

Ans: Given that $5$ pencils and $7$ pens together cost $Rs.\text{ 50}$, whereas $7$ pencils and $5$  pens together cost $Rs.\text{ 46}$.

We have to find the cost of one pencil and that of one pen.

Let the price of $1$ pencil be $Rs.\text{ x}$.

And, price of $1$ pen be $Rs.\text{ y}$.

Now, according to the question, total cost of $5$ pencils and $7$ pens together is $Rs.\text{ 50}$. 

Then we get

$5x+7y=50$ ……(1)

Also, total cost of $7$ pencils and $5$ pens together is $Rs.\text{ 46}$. 

Then we get

$7x+5y=46$ ……(2)

Now, the algebraic representation of equation (1) and (2) is

$5x+7y=50$

$\Rightarrow x=\dfrac{50-7y}{5}$ 

The solution table for the above equation is 

Now, for eq. (2)

$7x+5y=46$

$\Rightarrow x=\dfrac{46-5y}{7}$

The solution table for the above equation is 

Now, the graphical representation is

By observing the above graph we can say that the lines intersect each other at point $\left( 3,5 \right)$.

Therefore, the cost of one pencil is $Rs.\text{ 3}$ and cost of one pen is $Rs.\text{ 5}$.

2. On comparing the ratios $\dfrac{{{a}_{1}}}{{{a}_{2}}}$,$\dfrac{{{b}_{1}}}{{{b}_{2}}}$, and $\dfrac{{{c}_{1}}}{{{c}_{2}}}$, find out whether the lines representing the following pairs of linear equations at a point, are parallel or coincident:

(i) $5x-4y+8=0$

     $7x+6y-9=0$ 

Ans: Given pair of linear equations $5x-4y+8=0$ and $7x+6y-9=0$.

When we compare the given equations with the standard equations

${{a}_{1}}x+{{b}_{1}}y+{{c}_{1}}=0$ 

${{a}_{2}}x+{{b}_{2}}y+{{c}_{2}}=0$

We get

${{a}_{1}}=5$, ${{b}_{1}}=-4$, ${{c}_{1}}=8$

${{a}_{2}}=7$, ${{b}_{2}}=6$, ${{c}_{2}}=-9$

Now, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{5}{7}$, $\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{-4}{6}=\dfrac{-2}{3}$, $\dfrac{{{c}_{1}}}{{{c}_{2}}}=\dfrac{8}{-9}$

We get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}\ne \dfrac{{{b}_{1}}}{{{b}_{2}}}\ne \dfrac{{{c}_{1}}}{{{c}_{2}}}$

Therefore, the given pair of lines is intersecting each other and has a unique solution. 

(ii) $9x+3y+12=0$

      $18x+6y+24=0$ 

Ans: Given pair of linear equations $9x+3y+12=0$ and $18x+6y+24=0$.

When we compare the given equations with the standard equations

${{a}_{2}}x+{{b}_{2}}y+{{c}_{2}}=0$

We get

${{a}_{1}}=9$, ${{b}_{1}}=3$, ${{c}_{1}}=12$

${{a}_{2}}=18$, ${{b}_{2}}=6$, ${{c}_{2}}=24$

Now, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{9}{18}=\dfrac{1}{2}$,

$\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{3}{6}=\dfrac{1}{2}$, 

$\dfrac{{{c}_{1}}}{{{c}_{2}}}=\dfrac{12}{24}=\dfrac{1}{2}$

(iii) $6x-3y+10=0$

       $2x-y+9=0$ 

Ans: Given pair of linear equations $6x-3y+10=0$ and $2x-y+9=0$.

When we compare the given equations with the standard equations

${{a}_{1}}x+{{b}_{1}}y+{{c}_{1}}=0$ 

${{a}_{2}}x+{{b}_{2}}y+{{c}_{2}}=0$

We get

${{a}_{1}}=6$, ${{b}_{1}}=-3$, ${{c}_{1}}=10$

${{a}_{2}}=2$, ${{b}_{2}}=-1$, ${{c}_{2}}=9$

Now, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{6}{2}=\dfrac{3}{1}$,

$\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{-3}{-1}=\dfrac{3}{1}$, 

$\dfrac{{{c}_{1}}}{{{c}_{2}}}=\dfrac{10}{9}$

5. Half the perimeter of a rectangular garden, whose length is $4\text{ m}$ more than its width, is $\text{36 m}$. Find the dimensions of the garden.

Ans: We have to find the dimensions of a rectangular garden.

Now, according to the question length of a garden is $4\text{ m}$ more than its width.

Then, we get

6. Given the linear equation $2x+3y-8=0$, write another linear equations in two variables such that the geometrical representation of the pair so formed is: 

(i) Intersecting lines

Ans: Given linear equation is $2x+3y-8=0$.

We have to find the other linear equation which intersects the given line.

Now, we know that the necessary condition for the lines to intersect each other is  $\dfrac{{{a}_{1}}}{{{a}_{2}}}\ne \dfrac{{{b}_{1}}}{{{b}_{2}}}\ne \dfrac{{{c}_{1}}}{{{c}_{2}}}$

Now, assume that the second equation of line can be $2x+4y-6=0$.

Then, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{2}{2}=1$ and $\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{3}{4}$

Therefore, $\dfrac{{{a}_{1}}}{{{a}_{2}}}\ne \dfrac{{{b}_{1}}}{{{b}_{2}}}$.

(ii) Parallel lines

Ans: Given linear equation is $2x+3y-8=0$.

We have to find the other linear equation which is parallel to the given line.

Now, we know that the necessary condition for the lines to parallel to each other is  $\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{{{b}_{1}}}{{{b}_{2}}}\ne \dfrac{{{c}_{1}}}{{{c}_{2}}}$

Now, assume that the second equation of line can be $4x+6y-8=0$.

Then, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{2}{4}=\dfrac{1}{2}$,  $\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{3}{6}=\dfrac{1}{2}$, $\dfrac{{{c}_{1}}}{{{c}_{2}}}=\dfrac{-8}{-8}=1$

Therefore, $\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{{{b}_{1}}}{{{b}_{2}}}\ne \dfrac{{{c}_{1}}}{{{c}_{2}}}$.

(iii) Coincident lines

Ans: Given linear equation is $2x+3y-8=0$.

We have to find the other linear equation which is parallel to the given line.

Now, we know that the necessary condition for the lines to parallel to each other is  $\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{{{c}_{1}}}{{{c}_{2}}}$

Now, assume that the second equation of line can be $6x+9y-24=0$.

Then, we get

$\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{2}{6}=\dfrac{1}{3}$,  $\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{3}{9}=\dfrac{1}{3}$, $\dfrac{{{c}_{1}}}{{{c}_{2}}}=\dfrac{-8}{24}=\dfrac{1}{3}$

Therefore, $\dfrac{{{a}_{1}}}{{{a}_{2}}}=\dfrac{{{b}_{1}}}{{{b}_{2}}}=\dfrac{{{c}_{1}}}{{{c}_{2}}}$.

7. Draw the graphs of the equations $x-y+1=0$ and $3x+2y-12=0$. Determine the coordinates of the vertices of the triangle formed by these lines and the x-axis, and shade the triangular region.

Ans: We have to draw the graphs of the equations $x-y+1=0$ and $3x+2y-12=0$.

Now, the algebraic representation of equation is

$x-y+1=0$

$\Rightarrow x=y-1$ 

The solution table for the above equation is 

$3x+2y-12=0$

$\Rightarrow x=\dfrac{12-2y}{3}$

The solution table for the above equation is 

The graphic representation is as follows:

From the above graph, we can observe that the lines are intersecting each other at a point $\left( 2,3 \right)$ and x-axis at $\left( -1,0 \right)$ and $\left( 4,0 \right)$.

Therefore, we get the vertices of the triangle as $\left( 2,3 \right)$,$\left( -1,0 \right)$ and $\left( 4,0 \right)$.

An Overview of the Class 10 Maths Chapter 3 Exercise 3.2

We will look at the Graphical Method of Solving a Pair of Linear Equations in this exercise. We already know that a pair of linear equations will be graphically represented by two straight lines that can be parallel, intersect, or coincide.

Now, we will consider certain cases here.

• When two lines intersect each other at only one point, then we conclude that there is one and only one solution. It means that a unique solution exists for this pair of linear equations in two variables. This type of pair of linear equations is called a consistent pair of linear equations. 

• If the two lines are coincident, we can say that the pair of linear equations will have infinitely many solutions. This type of pair of linear equations can be called an inconsistent pair of linear equations. 

• If the two lines are parallel to each other, which means they do not meet at all, then we can say that the two linear equations will not have any common solution. This type of pair of linear equations will be called the dependent pair of linear equations.
