Question

Two girls have $76 between them. If the first gave the second $7 they would have the same amount of money.How much did each have

Answer 1

Find the money that both the girls will equally have.  

76/2 = 38

So, imagine this, take 7 dollars from girl 2 and give it back to girl 1, you would essentially to the opposite of what the question said.  

So, girl 2: 38 - 7 = 31

Girl 1: 38 + 7 = 45

To test if we got it right, add 31 and 46, and we get 76!
