Finding the max power generated

1. The problem statement, all variables and given/known data

Find the max power transferred through R in the circuit given.





2. Relevant equations



See attachment for the diagrams



3. The attempt at a solution



The Norton's equivalent resistance is 5.4Ω. For finding the Norton's current, I need to find the short-circuit current through the terminal AB.

Applying Kirchhoff's law to the middle loop, I can write

4(i-2)=1.43(5-i)

i=2.79



Thus, P = I_norton²R_eq = 42.04.

But this is the incorrect answer.
