Thevenin equivalent with two dependent sources

hi

I'm having some trouble figuring out the Thevenin equivalent for this circuit.

Circuit schematic with terminals a and b on the right, containing a 0.1i_o current-controlled current source, 10 Ω and 20 Ω resistors, a 40 Ω resistor, and a 2v_o voltage-controlled voltage source; v_o and i_o are marked.

As you can see, there are two dependent sources (current dependent current source & voltage dependent voltage source) and no independent source.

I have started trying to analyse the circuit by inserting a 1V source across the terminals "a" and "b".

With the 1 volt input across terminals "a" and "b", I have tried to determine the current entering the circuit to allow for determining the equivalent resistance of the circuit (Rth = 1V/Ix).

labelling the current through the 10 ohm resister i1 and the current though the 40 ohm resister i2.

Hand-drawn circuit schematic in red marker on a whiteboard, with node voltages V1, V2, V3, a 10 ohm and 40 ohm and 20 ohm resistor, a 0.1 Ix current source, a 2V0 voltage source and a 1V source with current Ix.

Thanks guys

I got it.
dont worry about this one.
... should I delete the thread?
if so, how?
