Question 80053: Two chemical storage tanks hold the same amount. Tank A is 3/4 full while tank B is 2/3 full The two tanks currently have a combined total of 1700 gallons of CO2. How much do the tanks hold?
I have tried so many formulas to solve this problem and none of them work. I get about as far as x=what the tanks hold. I've tried 3/4x + 2/3x = 1700 + x.

--------
Let the amount held by each tank be "x" gallons.
Tank A has (3/4)x gallons
Tank B has (2/3)x gallons
EQUATION:
(3/4)x+(2/3)x=1700
(9/12)x+(8/12)x=1700
(17/12)x=1700
(1/12)x=100
x=1200 gallons (each tank holds 1200 gallons)
Cheers,

3/4x+2/3x=1700 find a common denominator for the fractions (12)
(3*3+2*4)x/12=1700
(9+8)x/12=1700 now cross multiply
17x=1700*12
17x=20400
x=20400/17
x=1200 answer. the size of the tanks.
proof
3/4*1200+2/3*1200=1700
900+800=1700
1700=1700
