you have 23 coins and only quarters and nickels. How many quarter and how many nickels do you have for a total $2.85
------
Quantity Eq::: n + q = 23 coins
Value Eq::::: 5n +25q = 285 cents
------------------------------------
Modify:
n + q = 23
n +5q = 57
--------------
Subtract and solve for "q":
4q = 34
q = 8 1/2

Comment: There cannot be 8 1/2 quarters. Please check your post.
