conversations.value: Can you break down the solution for me for this math problem: John's piggy bank contains quarters, dimes, and nickels.  He has three more dimes than quarters and 6 fewer nickels than quarters.  If he has 63 coins, how many quarters does John have?
conversations.from: assistant
conversations.value: Let x represent the number of quarters John has
  Nickels: x-6
  Dimes: x+3
  Total:x+x-6+x+3=63
  3x-3=63
  3x=66
  x=22 quarters
