You can try trial and error.

a. 16 quarters, 13 dimes, 8 nickles = 37 coins *Nope. That isn't the answer.*

Keep going til you find the right answer.

Let x = number of dimes. Since the value of the coins does not matter, the quarters = x + 3, dimes = x and nickels = x-5.

(x + 3) + x + (x - 5) = 52

Solve for x.

I hope this helps. Thanks for asking.
