I understand how to solve these...kinda, how do you know what way the voltages are flowing? I always thought that wou were just suppose to draw a direction and the equations will work themselves out (Or is this just for resistor voltages?)

How do you know what way the voltages from the batteries are flowing, so I can set up KVL equations?

Thanks.
