Answer:
s = 42
Step-by-step explanation:
s-13=29
S is an unkown variable.
So something minus 13 equals 29.
we know that we can add/minus/mulitply/divide anything on one side, but we have to do it on the other side.
If we add 13 on both sides so we can cancel out -13. Because positive 13 minus 13 is equal to 0. But we also have to add 13 on the right side.
So s = 13+29
That's your answer.
