Welcome to AAC!

Is this school work?

Show your attempts at solving this. Start by applying KCL and/or KVL at each node. You do know what KCL/KVL means?

Master's degree? I thought Kirchhoff's laws were 1st year bachelor's degree.

Might be a module in another subject.

You shouldn't need it. This is something taught at the undergraduate level.

Is a guide to arrive to the master and i am solving

I will try to do with mesh

Like a foundation course?

I have a feeling he was kidding and picked a random whole number but i havent solved this network yet.

For example (via South Park 'AWESOM-O'):
Question:
"How much wood would a woodchuck chuck if a woodchuck could chuck wood?"

Yes you just need to apply some method of network analysis and that's the usual way to handle these kinds of problems.

I never touch mesh, and this is just a simple 2-node circuit as shown in the attached view. But imagine my surprise when one of the node voltages was shown to be 42! (actually 41.777777). But I was too tired to verify the answer.

Thank you do much for your help. With this I Will fight to solve it

I could verify it later sometime but you seem to have done a good enough job.

What techniques have you been taught / researched to solve these sort of problems

Hmmm, I get 41.81818, but yes, close to 42!

Now that you're rested up, have you verified your answer? This problem is the sort that can lead to sign confusion.

I think it was the sign confusion that induced my exhaustion. It seemed this problem was deliberately designed to lead one into making a polarity error (and it may have accomplished its purpose in my case.)

Are you saying that you made a polarity error, that there is not a node voltage near 42 volts?

No.
