## Main Question or Discussion Point

How do I find the line of intersection of two planes? I have an idea, but both of the planes have a -2z

ie. Plane 1: 10x-4y-2z=4 Plane 2: 14x+7y-2z

If I set them both equal to each other, I lose the z part. So, is there some other way to solve this, or am I missing something? Thanks!
