Question

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

Answer 1

Answer:

a) x = 5

b) x = 12

Step-by-step 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

Answer:

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

Step-by-step explanation:

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

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