thanks, yeah that is why I am asking the questionYou should have enough intuition by now to know that two planes cannot intersect at a point.
it's called "the normal equation". I got it on stackoverflow .comWhat you did looks like some sort of least squares fit. Where did you get that formula?
thanks but I need to use matricies. I am going to be calculating a few million intersections and I won't be able to do division since it is way too slow.If we add the two equations we get
thnaks that works greatThis is about as simple as it gets.

thanks2x + 1y +3z = 4
3x + -1y +4z = 6
[math]\begin{equation} \begin{matrix} 2 & 1 & 3 & | & 4 \\ 3 & {-1} & 4 & | & 6 \\ \end{matrix} \end{equation}[/math]
You can add the two rows, if that is what you want.
You need to understand that whatever you can do with the equations you can do with matrices.
