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
liubo4ka [24]

Answer:

C. Greg weighs 180 pounds, and Justin weighs 165 pounds

Step-by-step explanation:

let G be the weight of Greg and J be the weight of Justin

G -15=J

G/2 +75=J

G =J+15       (1)

G+150=2J.  (2)

If We substitute G by J+15 in equation (2) we will get:

G =J+15

J+15+150=2J

G =J+15

J+15+150=2J

G =J+15

J+165=2J

then J=165 and G=165+15=180
