Question

9) Arthur weighs 54 lbs. more than Lily. Their combined weight is 280 lbs. less than 6 times Lily’s weight. How much does Arthur weigh?

Answer 1

137.5 lbs.

Explanation:

Arthur = 54 + x

Lily = x

Arthur + Lily = 6x - 280

(54 + x) + x = 6x - 280

54 + x + x = 6x - 280

54 + 2x = 6x - 280

54 = 4x - 280

334 = 4x

83.5 = x

Arthur = 54 + x

Arthur = 54 + 83.5

Arthur = 137.5
