You can put this solution on YOUR website! The value (in cents) of the change in a purse that contains twice as many nickels as pennies, six more dimes than nickels, and as many quarters as dimes and nickels combined; p = number of pennies
--------------
Equations:
n = 2p
d = n+6
q = d + n
-------
Rearrange:
2p - n + 0 + 0 = 0
0 + n - d + 0 = -6
0 + n + d - q = 0
-----
You have 4 variables, so you need one more equation.
