Find the power dissipated by the 8 ohm resistor.

This was an example for source transformations.

2. Relevant equations

P=VI=V^2/r=I^2*R

V=IR

3. The attempt at a solution

First I transformed the 1 amp current source and 20 ohm in parallel

to a 20 V voltage source and a 20 ohm in series .

Then I added the two 20 ohms now in series for Req= 40 ohms.

Then I converted the 10 volt voltage source and the 10 ohm in series to a 1 amp current source in parallel with a 10 ohm resistor.

Now Im stuck , I dont feel like I should get the equiv.resistance of the 8 and 10 ohm resistors left in parallel ( because its asking for the power dissipated by the 8)

Can someone please guide me through this problem, what I'm doing wrong, or the proper approach.

Thank you
