You haven't really done much - you've equated the two equations, rearranged for x and then rearranged for y. The problem with this is you haven't got any coordinates at all, because you haven't eliminated the x or the y.

Try taking one of your equations and rearranging for x or y, substituting it into the second and seeing what you can do from there.

I tried it and got some neat answers, so let me know how you get on!
