How solve system 10 rational equations?

Equations are like$\displaystyle \frac{a \cdot x_i+b\cdot y_1 + c}{1+d \cdot x_i + e \cdot y_i}$. I tried it with multidimensional Newton-Raphson method but is unconvergent if I don't know rough solution. It need subdivision algorithm?

Sorry, but I don't see an equality sign, so I don't see any equation. Can you provide an example?

How about posting the entire problem while making sure there are no errors?

OP mentioned subdivision algorithm. Google's first link on that phrase is to the subject of approximating a surface with a polygonal mesh in graphics programming.

Question probably has something to do with that.

OP, you are asking a question specific to an application domain, namely computer graphics. The audience here in general doesn't have that background. It would be helpful to provide some context. What are you doing, what problem are you trying to solve, how does your formula (not an equation as Microm@ss notes) relate to your problem, and what specific aspect of your problem you need help with.
