there are two planes:(adsbygoogle = window.adsbygoogle || []).push({});

3x+y+z=1

3x+z=0

find a vectorUwith 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?
