**Reiny**, Monday, March 14, 2011 at 5:56pmIf "each has the same number of coins and Bill has the same number of dimes as Rosa has nickels", then

obviously Bill will have to have the same number of nickels as Rosa has dimes

Bill: number of dimes ---x , number of nickels ---y

Roas: number of dimes --y , number of nickels ---x

Bill equation: 10x + 5y = 90

Rosa equation: 10y + 5x = 75

I would double one of them and subtract, easy after that.
