Jeb has 25 coins.They are all quarters and nickels. He has a total of $2.85. How many quarters and nickels does he have?
------------
n + q = 25 --> q = 25-n
5n + 25q = 285
--------------
Sub for q in 2nd eqn
5n + 25(25-n) = 285
n + 5(25-n) = 57
n + 125 - 5n = 57
-4n = -68
n = 17 nickels
q = 8 quarters
