+1286 If I give my brother $8$ dollars, then we will have the same amount of money. If instead he gives me $19$ dollars, then I'll have twice as much money as he will have. How much money does my brother currently have (in dollars)?
+37147 y - 8 = b + 8 y ou give 8 and your b gains 8 to be equal
--- or --- y-b = 16
y + 19 = 2 ( b-19) or y-2b = - 57
subtract top equation from bottom to get - b = -73 or b = $ 73
