Substitute x-4 into the y place in 2x^2-xy=8
Then solve the equation using whatever method you like
Warning: you wont learn by just copying. Try first and don't copy it off from my spoiler. If you are still stuck, or you made it but wanna check, look below
I'd go for completing the square-
x=-2+2sqrt3 or -2-2sqrt3Last edited by C0balt; 24-09-2014 at 17:52.
