I think next would be to use algebra and the three equations to solve for each, right? So, I1 = .155 I2 = .332 I3 = .177 and this is amps, correct? Since it's current?

So for the next step, I think it is to write equations for the relationship between the individual loops, right? So for the right loop, would it be 15 I1 +20 I2 = 9 Volts ? and for the left, 20 I2 + 30 I3 = 12 Volts ?

I don't really understand but are you saying to have V=20*I2 - 15*I1 - 30*I3 ?

Okay, so at the bottom junction it looks like I1 and I3 are going in and I2 is leaving, so is the junction rule I1+I3=I2 ?

What do I do to start?

So the positive end on the 12 V is the left and the 9 V is the right. We haven't really done these in class at all...
