--------------
Quantity Eq: n = d + 5
----
Value Eq: 5n + 10d = 595 cents
-------------------
Substitute for "n" and solve for "d":
5(d+5) + 10d = 595
15d + 25 = 595
---
15d = 570
d = 30 (# of dimes)
---
Solve for "n":
n = d +5
n = 30+5
n = 35 (# of nickels)

Let the amount of dimes be D
Then the amount of nickels are 5D
Since the coins total $5.95, we then have: .1(D) + .05(5D) = 5.95
.1D + .25D = 5.95
.35D = 5.95
Therefore, D or dimes = =
and nickels = 17 * 5 =

Check
--------------
Dimes: 17 = 17 * 10_______$1.70
Nickels: 85 = 85 * 5______$4.25
Total of coins___________$5.95
