What are 2 possible consistent cases (one independent and one dependent) that can occur when 3 planes form a system?

What is the intersection of the planes, the type of solution, and what should be noticed in the algebra and matrices that I would form to make that conclusion?

I’m not sure what this question is even asking so if anyone could help out that would be great. I’ve been stuck on it for hours. Tried taking a break and coming back to it, completed my other homework questions but this one is wordy communication type of question which I’m not good with
