Use reasoning to lead to the answer of the following question:
Brenda weighs 10 pounds more than 3 times Mel's weight. If Brenda weighs 220 pounds, what is Mel's weight?

70
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.

.

The final answer: 70
