An aquarium tank is 1/6 full of water. When 2 gallons of water are added, the tank becomes 1/2 full. What is the total capacity of the aquarium tank, in gallons?
+10 Let the capacity of the aquarium tank be gallons.
Given that an aquarium tank is 1/6 of water and when 2 gallons of water are added, the tank becomes 1/2 full, so
x/6 + 2 = x/2 => x/2 - x/6 = 2 => 2x/6 = 2.
Thus, the total capacity of the aquarium tank be 6 gallons.
Hence, the total capacity of the aquarium tank be 6 gallons.
