Proportions
Tap A fills a tank in 4 hours. It means each hour it fills 1/4 of the tank.
Tap B fills the tank in 3 hours. Each hour it fills 1/3 of the tank.
Tap C empties the tank when full in 2 hours. Each hour it empties 1/2 of the tank.

The value of x is .
Solution:
Given expression is .
Switch both sides.
Subtract 8 from both side of the equation.
Divide by –3 on both side of the equation.
To cancel the cube root, raise the power 5 on both sides.
To find the value of x, take square root on both sides.
Hence the value of x is .
