Convert r^2=3/(tanx) into cartesian form.

I got this so far:
r^2=3/(tanx)
x^2+y^2=3x/y

What do I DO NEXT????

You could just leave it like that, or

x^2 y + y^3 = 3x
or y(x^2 + y^2) = 3x

just curious. Did they actually have tanx in the polar form and then asked for the cartesian form?
I would have expected something like
r^2 = 3/tanØ

If it actually was r^2 = 3/tanx
then it would be:
x^2 + y^2 = 3/tanx in Cartesian form
