Question

Find the value of x in each of the following
a) x + 3 = 8
b) X-5 = 7

Answer 1

a) x = 5

b) x = 12

Explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

Answer 2

`a)x = 5 \\ b)x = 12`

Explanation:

`a)x + 3 = 8 \\ x = 8 - 3 \\ x = 5`

`b)x - 5 = 7 \\ x = 7 + 5 \\ x = 12`
