What is the sum of all possible solutions of $\frac{9x}{13}+\frac{13}{9x}=\frac{250}{117x} + \frac{3x}{2}$?

Don't think i have the time to show the steps, but the sum of the possible solutions of that equation is 0.

You can move 3pi/2 and 9pi/13 to one side, and add them together, and then you can cross multiply, it's basic algebra.
