Question 715948
A gasoline tank is 1/4 full. After adding 10 gallons of gas the gauge now indicates, the tank is 2/3 full. What is the capacity of the tank. 
-----
Equation:
Let "x" be the capacity of the tank.
----
(1/4)x + 10 = (2/3)x
-----
Multiply thru by 12 to get:
3x + 120 = 8x
5x = 120
x = 24 gallons (capacity of the tank)
