----------------------------------------------------
He has two more quarters than dimes but three times as many nickels as quarters.
--------------------------------------------------

system%28q-d=2%2Cn%2Fq=3%2C25q%2B10d%2B5n=1080%29

Simplify E3, and substitute for d and n:
5q%2B2d%2Bn=216

5q%2B2%2A%28q-2%29%2B3q=216-----------one equation in one variable
