Question

Jim weighs 30 pounds less than Tom, and together they weigh 210 pounds. Let n Tom's weight in pounds. What would be the equation that expresses the total of Jim's and Tom's weights?

Answer 1

let tom be n

jim = n -30

jim + n = 210

n - 30 + n = 210 ( ah i guess this eqn is your ans)

2n = 240

n = 120

jim = 90
