A person has 20 coins, all nickels and dimes, worth $1.65. How many nickels are there?

BartSMP [9]

Let x represent the amount of dimes
Let y represent the amount of nickles

So since he has 20 coins, x + y = 20
and if we want to find the total money of dimes, we have to multiply x with 10

So 10x + 5y = 165 (in cents)
2x + y = 33
-x - y = -20
x = 13
so x = 13 and y = 7

Hope this helps :)
