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
