I posted this a few days ago and got no response. I've been working on it all week and still haven't come up with the right answer. If someone could show me how to step by step solve for this best answer will be rewarded.

Not exactly advanced...
I1=current thru R1, I2=current thru R2, I3 = current thru R3...
Starting at the point between the voltage sources and going clockwise on the top loop:
12-15I1-32I2=0
Starting at the same point and going counter-clockwise around the lower loop:
18-26I3-32I2=0
Finally, I2=I1+I3
3 equations in 3 unknowns...only algebra left.
