CBSE Class 10 Maths Chapter 3: Pair Of Linear Equations In Two Variables
Chapter Description: Linear equations in two variables are equations that can be expressed as ax + by + c = 0 where a, b and c are real numbers and both a and b are non-zero. The solution of such equations is a pair of values for x and y which makes both sides of the equation equal.
Let’s look at the solutions of some linear equations in two variables. Consider the equation 2x + 3y = 5. There are two variables in this equation, x and y.
- Scenario 1:Let’s substitute x = 1 and y = 1 in the LHS of the equation. Hence, 2(1) + 3(1) = 2 + 3 = 5 = RHS. Hence, we can conclude that x = 1 and y = 1 is a solution of the equation 2x + 3y = 5.
- Scenario 2: Let’s substitute x = 1 and y = 7 in the LHS of the equation. Hence, 2(1) + 3(7) = 2 + 21 = 23 ≠ RHS. Therefore, x = 1 and y = 7 is not a solution of the equation 2x + 3y = 5.
Geometrically, this means that the point (1, 1) lies on the line representing the equation 2x + 3y = 5 and the point (1, 7) does not lie on this line. In simple words, every solution of the equation is a point on the line representing it.
To generalize, each solution (x, y) of a linear equation in two variables, ax + by + c = 0, corresponds to a point on the line representing the equation and vice versa.
This chapter consists of seven exercises with the last exercise including an optional exercise. By the end of chapter 3, you will learn to solve pair of linear equations by graphical method (which will be solved on graph sheets) and algebraic method (using three methods). Lastly, you will also be able to solve the equations which are reducible to a pair of linear equations. The chapter has plenty of examples and exercise questions. So, go through the NCERT solutions for Class 10 Maths Chapter 3 if you have any doubts.
