1/2 of Alex's money was equal to 3/4 of Brayden's money. If Alex gave Brayden 5 dollars, then he would have 6 dollars less than Alex. How much did Brayden have at first?
(1/2)A = (3/4)B
A = ( 2/1) (3/4)B = (3/2)B (1)
So
A - 5 = B + 5 + 6 (2)
A - 5 + B + 11
Sub (1) into (2)
(3/2)B - 5 = B + 11
(3/2)B - B = 11 + 5
(1/2)B = 16
B = (16) (2/1) = $32 at first
