    I translated this as G=2W-12 and G+W=128 resulting in 128-W=2W-12

    70 is correct 128 = 2A-12 12+128 = 2A 140 = 2A 70 = A

    there formula, to me, implies 128 is just the weight of george

    Yes, combined weight is George and Adam. And you figured out that equation correctly the first time :)

    You bring it to the teachers attention and they lok it over and make the correction to your grade. Perfection is an ideal, not a reality :)
