Question 714372: On one of the farms outside of town, a water tank used for irrigation holds a total of 4568 gallons of water. The tank has 3 pipes through which the water drains to irrigate 3 different fields. Pipe B drains twice as much water as pipe A. Pipe C drains 68 gallons more than pipe B. Assume that the tank drains completely before it is refilled. How many gallons does each pipe drain from the tank?

You can put this solution on YOUR website!
g = gallons of water that tank A delivers to its territory.

Translation from description to expressions using variable, g:
Pipe A delivers g.
Pipe B delivers 2g.
Pipe C delivers 68+2g.

The sum of those gallons number expressions must equate to 4568 gallons total.
highlight%28g%2B2g%2B68%2B2g=4568%29

5g%2B68=4568
5g=4568-68
5g=4500
highlight%28g=900%29

FINAL ANSWER:
Pipe A, 900 gallons.
Pipe B, 1800 gallons.
Pipe C, 1868 gallons.
