RS Aggarwal Class 6 Math Ninth Chapter Linear Equation In One Variable Exercise 9B Solution

EXERCISE 9B

Solve each of the following equations and verify the answer in each case:

(1) x + 5 = 12

Solution: x + 5 = 12

Or, x = 12 – 5

Or, x = 7

(2) x + 3 = – 2

Or, x = -2 – 3

Or, x = – 5

(3) x – 7 = 6

Or, x = 6 + 7

Or, x = 13

(4) x – 2 = – 5

Or, x = – 5 + 2

Or, x = – 3





(15) 3(x+2)-2(x-1)=7

or,3x+6-2x+2=7

or,3x-2x+8=7

or,x=7-8

or,x=-1
