comment Kid's homework: 4 equations 5 unknowns? Going crazy!
There is no unique solution to that system of equations even if you limit yourself only to the natural numbers. I am posting just to confirm your observation, but concur with @naslundx.

comment Do rational functions separate points?
@Cantlog: That's really great and a clear, elegant proof at that. Why don't you post it as an answer, I'd accept in a heartbeat.

@AsalBeagDubh: Well. I wanted to avoid it, but if you have a solution for quasi-projective $X$, I'd be curious, too.

comment How to determine the local ring
It means localization in the multiplicative set $\{ x^k \mid k\in\mathbb N\}$. It is sometimes referred to as localization in $x$. It means adjoining $x^{-1}$, basically. Also, don't worry about questions ;).
