You can put this solution on YOUR website! A cylindrical water tank is 1/3 full. When 3500L was added to it, it bacme 5/7 full. What is the full capacity of the tank?
--------------------
Let the full capacity be "x".
---
Equation:
(1/3)x + 3500 = (5/7)x
---
(1/3)x - (5/7)x = -3500
---
(-8/21)x = -3500
x = (21/8)3500
x = 9187.5 L
