Homework Help: math

Posted by Anonymous on Sunday, January 27, 2008 at 10:14am.

1)y=x-3x+2
2)y=8x-16/x-3

A)Sketch both on axes
B)Calculate coordinate of points of intersection

I have drawn both on axes. I am having trouble with B). I know you have to do y=y.

So far i have done this;
x-3x+2=8x-16/x-3
(x-3)(x-3x+2)=8x-16
x-6x+11x-6=8x-16
x-6x+3x=-16
x-6x+3x+16=0

what do i do now?
