I have to simplify the circuit using source transformation and then find the current ix.
I have attached my attempted solutions but I do not get the correct answer of ix = 0.9A ( I am getting 4.3 amps now).
What I suppose I would like to know is:
Is my circuit simplification correct or have I made a mistake somewhere?
Or could I have solved the current ix easily from any of the earlier steps I made in my circuit simplification? i.e. when would you guys stop performing source transformation and circuit simplification and start with circuit analysis to solve the current ix?
