Question

Justin weighs 15 pounds less than Greg weighs. Half of Greg’s weight is 75 pounds less than Justin’s weight. How much does each of them weigh?

Answer 1

To answer the problem, let x be Justin's weight and y be Greg's weight.
From the first case,
x = y -15

Translating the second condition mathematically,
0.5y = x - 75

Solving for x and y simultaneously, will give
x = 165 pounds and y = 180 pounds.

Thus, Justin and Greg weigh 165 pounds and 180 pounds, respectively.
