22= 2x=8

subtract 8 from both sides

14=2x

divide both sides by 2

7=x

2x + 8 = 22

The answer is what number 'x' must be.
Here's one way to find out:

Subtract 8 from each side : 2x = 14

Divide each side by 2 : x = 7

That's the only possible number that 'x' can be.
If 'x' is any other number, then 2x+8 is not 22 .
