A collection of nickels, dimes, and quarters consists of 14 coins with a total value of $1.75. If the number of dimes is equal to the number of nickels, find the number of each type of coin. 
Equations:
Quantity:: n + d + q = 14 coins
Value:::: 5n +10d+25q = 175 cents
Quantity:: n - d + 0 = 0
----------------------------
Solve by any method to get:
n = 5
d = 5
q = 4
