The sum of Eric and Bob's weights is 9 times greater than the difference of their weights. The positive difference of their weights is also 240 pounds less than the sum. If Eric weighs less than Bob, find Bob's weight.
I am not sure at all how to solve this, especially how to make sure that Eric weighs less than Bob in the equation. Please help! Thanks! :-)
