I'm new to the forum. I have what looks to be a relatively simple circuit and asked to find the Thevenin equivalent.

I'm really struggling with both of them. But I just want to talk about the first - number 10.

As far as I can gather, with dependent only sources - you should add a current or voltage source. I added a 1 amp source - at Voc, between a and b, pointing toward a.

After that you have to get the voltage drop across the amp source (not sure if that's correct)

Anyways, I've tried -

nodal analysis on this sucker.

KVLs,

tried writing the currents in terms of ix and substituting values in and all sorts of fun stuff currently 5 pages long.

The math just keeps coming out with zero values and all sorts of gooey nonsense / and / or / too many unknowns.

I'm sure this is something really profound, that I'm supposed to realize with this, but I sure don't have a clue what it is. Can someone just please, push me in the general direction, I should be taking with this.
