Optics: deriving Nodal and Principal Points for a thick lens

[Arman777]

Homework Statement

I have to derive the Nodal and Principle points distance equations.

Homework Equations

Equations can be found here

The Attempt at a Solution

I have no clue about how to approach this problem. If there's any starter hint that you can give me, that would be great, then I can maybe derive it myself. Just I don't know how to start.
We can use matrix method or general equations for thick lens etc.

Thanks

Please make an attempt. It is difficult to help you otherwise. You could start by writing down whatever you know about thick lenses, principal points and nodal points (in equation form, if possible).
