Question

If x + 4 = 12, what is the value of x?

Answer 1

8

Explanation:

x+4=12, so 12-4=x (if you use an the inverse operation of addition, subtraction.)

12-4=x, so all you have to do is subtract and, there you have it, 8. It makes sense, 8+4=12. :)

Answer 2

x = 8

Explanation:

x + 4 = 12

x=12-4

x=8
