This is such a typical problem from a network theorem book!!! What so special? It's not even hard!!! You see this kind of problem when you study Thev., Norton, super position, nodal analysis etc.

Oh man it confuses me a lot i tried a lot to solve it... I have no idea how to do it.. >.< Do you mind giving me a hand?

Thanks

I was wrong on the right side, you need to use Source Transformation instead of Norton.

http://en.wikipedia.org/wiki/Source_transformation

You have to at least try. For example on the right side, you need to read Thevnin Theorem and find the $R_{th} \;,\; V_{th}$.

Ignor the 6ΩW at the bottom and look at the left side, if you want to find the Rth, short out the 10V and find the resistance. It would be 10Ω//5Ω+3Ω≈6.333Ω.

If you want to find Vth, read the voltage from a to the junction of the 5Ω and 6Ω. I'll let you tell me the voltage.

Read the link I gave you and work on it then come back.
