Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
total (x) amount = (n)ickels + (q)uarters + (d)imes + (p)ennies
*** <--- amount of nickels plus 16 coins = total amount of coins
this means that the other 16 coins are made up of quarters dimes and pennies
amount of quarters plus 16 coins = total amount of coins
this means that the other 16 coins are made up of nickels dimes and pennies
amount of dimes plus 16 coins = total amount of coins
this means that the other 16 coins are made up of nickels quarters and pennies
amount of pennies plus 18 coins = total amount of coins
this means that the other 18 coins are made up of nickels quarters and dimes
.
Deducing from above set values of x against values of x to find what each amount is equal to

d+16=n+16=q+16
d=n=q so the amount of dimes/nickels/quarters are all the same amount
this means its like saying
*** <--- I chose (n)ickels as it was the first equation

*** <---
combining the 3 (***)<--- values I made this equation.

if n=6 then:

Correct
