Ben has a collection of quarters and nickles worth $5.35. If the number of nickles is five less than twice the number of quarters, find the number of each coin.
------------------
25q + 5n = 535 cents
n = 2q - 5
----------------------
Substitute::
25q + 5(2q-5) = 535
25q + 10q - 25 = 535
35q = 560
q = 16 (# of quarters)
---------------
n = 2q - 5
n = 32-5
n = 27 (# of nickels)
