Question

Al and Alice went to a "being a Snack" party. Al spent 10 pennies + 16 dimes. Alice spent as much as Al, but her 26 coins consisted of only quarters and nickels, How many nickels did Alice spend?
q+n = 26
25q+5n = 10*1 + 16*10

25(26-n)+5n = 170
I expect you can take it from there, right?
