We go through solving a circuit which only containes independent sources: two voltage sources and two current sources. KVL and KCL are used to determine voltages and currents.
Determine the amount of power absorbed or supplied by each source.

Determine the amount of power absorbed or supplied by each source.
Find the voltage across the current source and the current passing through the voltage source.
Assume that ,
