If I give my brother 5 dollars, then we will have the same amount of money. If instead, he gives me 14 dollars, then I'll have three times as much money as he will have. How much money does my brother currently have (in dollars)?

Y=You,   B = Brother

 

Y - 5 = B + 5

Y + 14 =3[B - 14], solve for Y, B

 

Y =$43 - what you started with

B=$33 - what your brother started with.

 

[43 - 5] = [33 + 5] - you would have the same amount of money if $5 changed hands

 

43 + 14 = $57 - what you have now after getting $14 from your brother, which is 3 times what your brother has.

 

33 - 14 = $19 - what your brother has after giving you $14.
