Tried doing a quick check using your calculated node voltages:

Vb=22.91
Vd=46.617
Ve=23.952

The current flowing out of node D equals (46.617-23.952)/4K = 5.67mA.
The current flowing into node D equals 20 + 4((22.91-6)-23.952)/2 = 5.92mA.
Is that close enough for homework?

You made a typo when you copied Vd from your calculator to the third jpg image. It should be 47.617. Fix this and show a little more detail in your power calculation--it seems a little high. Your currents are mostly milliamperes. :)
