Response Details:
You can do this problem in 1 step. All you need to do is a nodal analysis starting at the middle node.

The equation is:



2v - 20 + v - 2 + v - 15 = 0         =>         4v = 37         =>      v = 9.25 V


Therefore, the voltage across the 5Ω is (10 - 9.25) = 0.75 V

The end closer to the the voltage source has higher potential (10 V). The end closer to them middle node is 9.25 V
