Hello again...I posted a couple of problems that I have attempted. I think I have a better handle on these ones, but was hoping could let me know if i am right or not.

Here is what I have so far
Thanks again

8.1
circuit 1:
Voltage at A = 1.0V
Voltage at B = .5V

circuit 2:
Voltage at A = 1.5V
Voltage at B = 1.0V


8.2
circuit 1:
Voltage at A = 1.2V
Voltage at B = .3V

circuit 2 is where I seem to not understand. I do get that the voltage at A can equal either:

Va = 2.4V + Vb
or
Va = 2.7V + Vc

Va - Vb = 2.4V
Va- Vc = 2.7V

how do i go further than this?

Everything looks good. As far as 8.2 circuit 2 I can't get any further than you did. Your work up to that point is correct, however.
