Using superposition find the voltage across the 6A source.

Firstly I shorted the 12V source and placed an open circuit on the current source leaving only the 8V source. I worked out a total resistance of 2.916 Ohms. Does anyone tell me if this is correct. Then a source current of 2.743A. If I got these values correct I could probably continue okay. Can anyone tell me if they are correct.

Also with only the 8V source I got the current across the 6A source to be 2.74A when I simplified the circuit. Is this correct?

Please help. Thanks

 

when only 8 v is considered.
30 parallels 6=5
4 is in series:5+4=9.
this 9 is in parallel to 12 ohms.
=5.14 something.
this is in series with 4 ohms=9.14 something.

Also with only the 8V source I got the current across the 6A source to be 2.74A when I simplified the circuit. Is this correct?

a 6A source will have 6 A thru it.
