How Do You Use the Superposition Theorem in Circuit Analysis?

In the problem attached do you use superposition theorem.
if so how do you use it?
I don't know how to solve circuits with 2 voltages.

Nah. Just write the KCL equation for the node between R1 and R2 and solve.

thanks for the reply. which voltage do I use?

Have you learned how to write the KCL equations yet for a circuit?

You write the equation that shows that the sum of all curents out of a node is zero. So in your problem, label the node between R1 and R2 as "Vx", and write the equation that shows that the sum of the 3 currents *out* of that node add to zero. Then solve away!
