finding Ix after source conversion

Hi

I'm really stuck here.

I was trying to solve this circuit for finding Ix. Please check this link:

There could be two ways t solve this. One is that I convert 2Ix dependent voltage source into a current source, or convert 4A current source into a voltage source. Frankly speaking, I don't know how to find Ix. Please help me. I have redrawn the circuit after source conversions but don't know if they are correct. Please help. It would really kind of you.

Ix+2Ix=4
3Ix=4
Ix=4/3

The resistor values are irrelevant.
