Question

Barry’s mountain bike weighs 6 pounds more than Andy’s. If their bikes weigh 42 pounds altogether, how much does Barry’s bike weigh? Identify the if-then moves in your solution

Answer 1

36 because if x=42-6 you subtract

Answer 2

The equation to solve this problem would be x+6=42. So, Barry's bike would weigh 36 pounds.

I don't know what if-then moves are. Maybe you can that yourself?
