Question

What are the inverse operations necessary to solve the equation four times s minus nine equals thirteen?

Answer 1

4s - 9 = 13

Answer 2

Add nine to both sides in order to retain terms with s on the left side without any terms with s on the righthand side.

After that, you divide by 4 to end up with something that looks like s = ...

Problem solved. Is this what you are looking for ?

Answer 3

4s=22
s=22/4

divide 22 with 4
s=?
