**Summary::**Current through a certain resistor in a mixed dc circuit.

Hi, Sorry if this is the wrong forum.

I'm trying to work out the current through R1.The answer I need is 2 Amp, which I have confirmed with a simulation software.

I have calculated the source current as 8A, the current past R3 as 4.44...A and finally R1 as 2.22...A.

Can anyone tell me what I am doing wrong please?

thanks
