Tim's piggy bank contains quarters and nickels worth ​$6.10 He has 50 coins in all. Which system of equations models this​ problem? How many of each coin does Tim ​have?
---------------------
Quantity Eq:: n + q = 50 coins
Value Eq:: 5n + 25q = 610 cents
--------------------------------------
Modify for elimination::
n + q = 50
n + 5q = 124
----------------------
4q = 74
q = 18 1/2 (note: This is not an acceptable answer for "# of quarters)
------------------------
