there are two planes:
3x+y+z=1
3x+z=0
find a vector U with positive first coordinate that is parallel to both planes.
the way I went about solving this:
the normal vectors are: <3,1,1> and <3,0,1>, the cross product of the vectors will give a vector perpendicular to the normal, which means it would be parallel to the two planes right?
