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 .
22= 2x=8

subtract 8 from both sides

14=2x

divide both sides by 2

7=x
