I've got this parametric equations:

$\displaystyle x=\frac{c(t^4+1)}{2t^3}$

$\displaystyle y=\frac{c(t^4+1)}{2t}$

t is the variable

I am supposed to find the Cartesian equation of these points, are there any pointers like things to look out for when trying to convert such things? I want to try it myself, but i need some guidance as to where to start when dealing with such equations.

Thanks!
