Ok, I have been trying to solve this equation for almost a month now, even my math teacher don't know how to solve it, and it seem I'm not getting closer to an answer, so I decided to look for help on the internet.

Anyway, here is the equation I'm trying to solve (sorry if I posted this wrong, but it seems like it's worse to post a easy question in the hard question forum then the reverse),

(1200/x^1)+(1100/x^2)+(1000/x^3)+(900/x^4)+(800/x^5)=3098 (X=1.2)
