Question 499001: Two tanks hold a total of 54 gallons of a toxic solvent. One tank holds 9 gallons more than twice the amount in the other. How many gallons does each tank hold? Answer by deborabr(181) (Show Source):
You can put this solution on YOUR website! tank 1 = x
tank 2 = y
x+y=54
y=9+2x
x+9+2x=54
3x=54-9
3x=45
x=45/3
x=15
substituting x to find y
y=9+2x
y=9+2*15
y=9+30
y=39
one tank holds 15 gallons and the other tank holds 39 gallons
