n = nickels
q = quarters
n + q = 26
q = 26 - n
5n + 25q = 350 > substitute first equation into this equation
_________________________________________
5n + 25(26 - n) = 350
5n + 650 - 25n = 350
-20n + 650 = 350
-650 -650
________________________
-20n = -300
_____ ______
-20 -20
n = 15
Now solve for q. Use either equation.
q = 26 - n
q = 26 - 15
q = 11
