Solving Kirchhoff's Rules: Electric Circuits and Algebra Practice

[teken894]

This is a problem from my physics book. We are learning Kirchhoff's rules with electric circuits and I'm at a loss at what to do here.

I apply them just fine to a three loop circuit, using some algebra:
|-/\/\-|\//\ -|
| |
|--|\--/\/\/--|
| |
|---|\--/\/\--|

Like so..where |\ is a battery and /\/\ indicate resistors. I can find the current in a similar circuit, voltage drops, etc

But this problem:

I don't know where to begin..or how to apply the rules. Can someone help me in finding the terminal voltage of the batteries??

Thanks

You have to sum the drops across each circuit element. What is terminal voltage and how is it defined mathematically for an emf E with internal resistance r for which current i is flowing out of the positive terminal?
