Thevenin stuff, right?

3. The attempt at a solution

So, I tried to re-write everything and make it a bit easier to understand:

I ended up getting Rth completely fine and everything, but I can't seem to get Eth.

So from there, I figured that I simply do like other problems that have 2 voltage sources. Simply act as if all the other sources are pieces of wire while leaving one at a time actually there, getting the voltage, etc.

The only thing about this is, I assumed that the voltage of AB is the same as the voltage of the6.8K resistor. When I looked over other examples, all of which only had 2 voltage sources, the voltage of AB was simply the voltage of a resistor in the same place that the 6.8K resistor was. But the thing is, in those examples, there were only 2...Not sure if that messes things up =(

So then because E1 had a positive polarity, E2 had a negative, and E3 had a positive, I added E1 and E2, then subtracted E2. When I did this, I simply got the completely wrong answer. Rth was fine, but Eth is just plain completely wrong. The book says that Eth should be 9.74V. I got like 12 something =(

Help? =(
