Paul and Justin had the same amount of money. After Paul spent $44 and Justin spent $60, Paul had 2 times as much money as Justin. How much money did each have at first?

P = J

P - 44 = 2 ( J - 60)

Sub J for P

J - 44 = 2 ( J - 60) simpify

J - 44 = 2J - 120

120 - 44 = 2J - J

76 = J = P

They both had $76

Proof

76 - 44 = 2 ( 76 - 60)

32 = 2 ( 16) which is true
