V = 8V
I0 = 4A

1. Since there are only two nodes, it seems appropriate to apply KCL.
2. Alternatively you can transform the 6A current source into voltage source and then apply KVL

The attachment shows the solution using the first method (ie. by applying KCL)

how do I transform that 6A current source into a voltage source?

thanks! how nice of you to put time and effort to help! regards!

anyways, how do I transform that 6A current source into a voltage source?
 

To convert a current source in parallel with a resistor to its equivalent voltage source we find its Thevinin's equivalent.
This simply results in a voltage source in series with the same resistor
The voltage is given simply by IR

Yes, use the node method. There is only one node. Once you find the voltage of the node, then you can find all the currents in the branches.

Current going into the node equals the current leaving the node (KCL). Six amps are entering the node, V/2 +(1/4)*(V/2)+V/8 amps are leaving the node. Can you find V now?
