These two plane normals are not parallel. *)
Thus, the planes are not parallel.
Assume you can draw a third plane (this problem) parallel to both.
Then the first one is parallel with third one.
And the second one is parallel with third one.
Thus, the first one is parallel with second one.
But that is a contradiction!
Thus there is no answer to your question.
*)The vectors are not scalar multiples of each other.
Do you mean that I should find two seperate planes, one parallel with first one and another parallel with second one. So they pass through the point (-1,-2,3).
