Important Definition for RS Aggarwal Chapter 3 Class 10 Maths Ex 3b Solutions

Substitution Method

An equation can be solved by this method when you find one variable from either equation and substitute its value in the other equation.

For instance, x+2y=3 and 4x+5y=6

Step 1: Let’s consider equation (1), x+2y=3

So we write as x=3-2y

Step 2: Substituting the value of x in equation (2),  4x+5y=6

We have 4(3-2y)+5y=6

12-8y+5y=6

12-3y=6

y=2

Step 3: Substituting the value of y in x=3-2y, we have x= 1

Elimination Method

This method is considered more convenient. It is solved by multiplying both the equations by some non zero constant and after that adding or subtracting one equation from another to eliminate one variable. By solving one variable you obtain the value of another variable by substitution.
