Examples of Class 8 Linear Equations in One Variable

Here are some common examples of Class 8 Linear Equations questions:

Q. A rational number has an eight times larger denominator than its numerator. The result is 3/2 if the numerator is raised by 17 and the denominator is lowered by 1. Find the rational number.

Solution:

The denominator will be (x + 8) if the numerator is x.

As given,

(x + 17)/(x + 8 - 1) = 3/2

⇒ (x + 17)/(x + 7) = 3/2

⇒ 2(x + 17) = 3(x + 7)

⇒ 2x + 34 = 3x + 21

⇒ 34 - 21 = 3x - 2x

⇒ 13 = x

The rational number is 13/21 (or x/(x + 8)).

 

Q.(3y + 4)/(2 – 6y) = -2/5

Solution:

(3y + 4)/(2 – 6y) = -2/5

⇒ 3y + 4 = -2/5 (2 – 6y)

⇒ 5(3y + 4) = -2(2 – 6y)

⇒ 15y + 20 = -4 + 12y

⇒ 15y – 12y = -4 – 20

⇒ 3y = -24

⇒ y = -8

 

Q. (7y + 4)/(y + 2) = -4/3

Solution:

(7y + 4)/(y + 2) = -4/3

⇒ 7y + 4 = -4/3 (y + 2)

⇒ 3(7y + 4) = -4(y + 2)

⇒ 21y + 12 = -4y – 8

⇒ 21y + 4y = -8 – 12

⇒ 25y = -20

⇒ y = -20/25 = -4/5

 

Q. The ratio between Hari and Harry's ages is 5:7. Their ages will be proportionately 3:4 in four years. What is their age right now?

Solution:

Let Harry's age be seven times that of Hari. After four years,

Age of Hari = 5 times + 4 Age of Harry =7 x + 4

As given,

(5x + 4)/(7x + 4) = ¾

⇒ 4(5x + 4) = 3(7x + 4)

⇒ 20x + 16 = 21x + 12

⇒ 21x - 20x = 16 - 12

⇒ x = 4

Hari age is 5x, or i.e., 5* 4 years = 20 years

Age of Harry = 7x = 7*4 = 28 years.

 

Q. 3(t – 3) = 5(2t + 1)

Solution:

3(t – 3) = 5(2t + 1)

⇒ 3t – 9 = 10t + 5

⇒ 3t – 10t = 5 + 9

⇒ -7t = 14

⇒ t = 14/-7

⇒ t = -2

FAQs on CBSE Class 8 Maths Worksheet Chapter 2 Linear Equations in One Variable - PDF

1. What primary subjects are addressed in Chapter 2 of the NCERT Solutions for Class 8 Math?

There are 6 problems in Chapter 2 of the NCERT Solutions for Class 8 Maths that deal with linear equations in one variable. The key ideas presented in this chapter are: 2.1 The Start 2.2 Solving Equations with Numbers and Linear Expressions on One Side 2.3 Some Applications Solving Equations with a Variable on Both Sides, Section 2.4 2.5 A Few Additional Uses 2.6 Simplification Equations Equations Reduced to Linear Form, Section 2.7.

2. What is the one-variable solution to a linear equation?

A linear equation with one variable has the usual form Ax + B = 0. Here, x is the variable, A is its coefficient, and B is its constant term.

3. How are linear equations with one variable solved?

The following are the steps to solving linear equations in one variable worksheet:

  • By adding and subtracting on both sides of the equation, keep the variable term on one side and the constants on the other.

  • Make the constant terms simpler.

  • By multiplying or dividing the same term into both sides of the equation.

  • Simplify, then type the response.

4. Can there be more than one variable in a linear equation?

Yes, there can be more than one variable in a linear equation. Such equations are referred to as linear equations in two or three variables. The two-variable linear equations have the form ax + by + c = 0, while the three-variable linear equation has the form ax + by + cz + d = 0. Here, the variables are x, y, and z; the coefficients are a, b, and c; and the constant is d. These linear equations are frequently utilized in linear programming to obtain the best solutions.

5. What is the power of a variable in a linear equation in one variable?

In a linear equation with just one variable, the variable's power is 1. For instance, the power of the variable "a" in the equation 3a + 4 = 11 is 1.
