Homework Statement

Hello, how to find the distance between two planes when given their cartesian equations?

help appreciated, thanks.

hints:

you might as well consider planes that are parallel to each other so...

transform the problem into something simpler... instead of looking at distance between two planes, choose something on one plane and go from there.
