Let A  be tthe amount that one brother has

 

Let  A + 15  be the amount the other brother has

 

And the combined amount  =   55    .....so.....

 

A  + ( A + 15)   =   55         simplify

 

2A  +  15   =    55       subtract 15 from both sides

 

2A  =  40       divide both sides by 2

 

A  = 20  

 

And  A + 15  =  20 +  15  =  35

 

So...one has saved $20  and the other has saved $35

 

cool cool cool
