Greetings, I am have a bit of a problem getting started on the following problem. The only thing that is confusing me is I am use to seeing a problem like this be perpendicular to 1 plane and not 2.

The problem I am working with is as follows:

I just need some direction on where to start.

Edit:

I am not quite sure what to do with both planes given.

The final equation should look similar to the following, correct?:

?(x-0)+?(y-0)+?(z-0)=0. Again, I am not sure how to come up with the coefficients using two given planes.

I spent about 4 hours on this problem and feel really lost and stupid!

The problem I am working with is as follows:

**Find the equation of a plane through the origin and perpendicular to the planes given by x-y+z=5 and 2x+y-2z=7.**I just need some direction on where to start.
