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
