q, n, d;
for quarters, nickels, dimes

system%28q%2Fn=2%2Cd-q=1%2C25q%2B10d%2B5n=610%29

system%28n=q%2F2%2Cd=q%2B1%2C5q%2B2d%2Bn=122%29

5q%2B2%28q%2B1%29%2Bq%2F2=122------one equation in only one variable
10q%2B4%28q%2B1%29%2Bq=244
15q%2B4=244
15q=240
highlight%28q=16%29-----------quarters
-
highlight%28d=17%29----------dimes
-
highlight%28n=8%29----------nickels
