## What are The Topics Covered in RD Sharma Solutions for Class 9 Maths Chapter 13 Linear Equations in Two Variables?

The topics covered in RD Sharma Solutions for Class 9 Maths Chapter 13 are given below:

• Linear Equations in Two Variables Introduction.

• Solution of a linear equation.

• Graph of a linear equation in two variables.

• Equations of lines parallel to the x-axis and y-axis.

### What is The Unique Solution to Two-Variable Linear Equations?

In the given line equations of two variables, the solution will differ for both equations, if and only if they intersect at the same point. The condition for obtaining a unique solution for a given line calculation is that a slope of a line made up of two calculations, respectively, should not be equal.

### Solutions of Linear Equations in Two Variables:

The solution of two dynamic line arithmetic ax + by = c is a point on the graph so that when x-coordinate is multiplied by a and y-coordinate is multiplied by b, then the sum of these two numbers is equal to c., in two dynamic line calculations, there are infinitely more solutions.

For example, to find the Linear equation solution in 2 variables, two figures must be known to us.

Consider an Example:

5x + 3y = 30

The above number has two variables namely x and y. figuratively this figure can be represented by a variable change into zero.

The value of x if y = 0 is

5x + 3 (0) = 30

⇒ x = 6 and the value of y if x = 0 says,

5 (0) + 3y = 30

⇒ y = 10

It is now understood that to solve two line numbers, these two numbers must be identified and the replacement method followed. Let us consider this with a few examples of questions.

### How Can Linear Equations in Two Variables be Used in Real Life?

Linear equations in two variables can be a useful tool for comparing earnings. For example, if one company promises to pay you  ﹩450 a week and another gives you ﹩10 an hour, and both ask you to work 40 hours a week, which company offers the best salary? Line number can help you find it. Identify keywords and phrases, translate sentences into math problems, and develop problem-solving strategies. Solve word problems that involve relationships between numbers. Solve geometric problems involving perimeter.

5. Write the number of the line corresponding to the x-axis and then across the space.

(i) (0.3)

(ii) (0, −4)

(iii) (2, −5)

(iv) (3, 4)

(i) The coordinates for a Cartesian plane are given (0,3).

For the equation of the line corresponding to the x-axis, we assume the number as one variable number independent of x containing y equal to 3.

We find the equation as

y=3
