Question

What number should be added to both sides of the following equation to solve for g?

g - 18 = 25

43
6
18
25

Answer 1

18. what is done to one side must be done to the other side, so when you add 18 to the left to cancel it out, you must add it to the right as well.

Answer 2

18

Explanation:

Since you are subtracting -18, and need to make it reach a zero to isolate g, you add 18.

Hope that helps! :)
