SUMMARY
The discussion focuses on determining the Thevenin equivalent circuit for a configuration involving a current source. The key approach involves finding the voltage across the terminals, specifically the voltage across the 5I_x element. Participants suggest using nodal analysis to derive the output node voltage expression in the form Vo = V_{th} (Z_L / (Z_L + Z_{th})), which simplifies the process of isolating Vth and Zth.

You will want to find the voltage across the terminals, which would merely be the voltage across the 5I_x element.

Nodal analysis looks promising.
If you slap a load impedance ZL onto the output and can wrestle the output node voltage expression into the form:
Vo = V_{th} \frac{Z_L}{Z_L + Z_{th}}
then you're golden. It may take some creative grouping of terms to isolate the Vth and Zth bits
