Sam has $2.05 in quarters and dimes. He has 4 more quarters than dimes. Find the number he has of each coin
====================================
Quantity Eq:: q = d + 4
Value Eq:::: 25q+10d = 205
-----------------------------------
Substitute for "q" and solve for "d":
25(d+4) + 10d = 205
35d = 105
---
d = 3 (# of dimes)
----
Since q = d+4, q = 7 (# of quarters)
