conversations.value: Brenda weighs 10 pounds more than 3 times Mel's weight. If Brenda weighs 220 pounds, what is Mel's weight?
  What is the solution?
conversations.from: assistant
conversations.value: Let Mel's weight be m
  Brenda’s weight is 3*m + 10 = 220 pounds
  Thus 3m = 220 - 10 = 210 pounds
  Therefore Mel's weight is m = 210/3 = 70 pounds
