In the photos are the questions. any ideas how to tackle?

 

Do you have any intention of making any attempt to answer any of your homework problems?

We can wait. Post your best attempt when you can and we'll proceed from there.

 

attempt on the first question: with photos
the voltages rotate, so each side get all 6 voltages.
i got the voltages at x to be
3.385v (by: 4.3/5 + 4.7/4 + 2.7/2)
the Highest x = 8.025v = 5.3/1 + 1.7/2 + 3.7/4 + 5.7/6
5.75v
5.9183v
4.233v
and 3.86v

Are they correct? is there other approach that someone can advise me with?
