You can put this solution on YOUR website! An aquarium filled to the brim with water weighs 108 lbs.
The same vessel half-filled weighs 57 lbs. How much does the empty aquarium weigh?
:
let x = weight of the aquarium
:
108 - x = 2(57 - x)
108 - x = 114 - 2x
-x + 2x = 114 - 108
x = 6 lb is weight of the empty aquarium
