Given, x -2 = 7

=> x – 2 + 2= 7 + 2    [Adding 2 both sides]

=> x = 9

Question 2:

Solve of the following:    y + 3 = 10

Solution:

Given, y + 3 = 10

=> y + 3 – 3 = 10 – 3 [subtracting 3 on both side]

=> y = 7

Question 3:

Solve the following:     6 = z + 2

Answer:

Given, 6 = 2 + z

=> 6 – 2 = z + 2 – 2     [Subtracting 2 both sides]

=> 4 = z

=> z = 4

Question 4:

Solve the following:     3/7 + x = 17/7
