There are 60 nickels, dimes, and quarters totaling $7.20. If there are five times as many quarters as dimes, how many nickels are there?

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

answer:

step-by-step explanation:
