Question

(07.01)
What is the value of z in the equation z - 3 = 22?

Answer 1

z=25

Add 3 to both sides

z-3+3=22+3

z=25

Answer 2

z=25

Explanation:

All you got to do is the opposite of subtraction. Which is addition. So, just add 3 to 22, and because you are doing the opposite, the -3 crosses out.

22+3=25

So z=25
