Troubleshooting Circuit with Kirchhoff's Laws

[Kokoska]

Hello, I am quite confused about this circuit:

It's quite possible, that this circuit doesn't make any sense, it was made by me, out of curiosity.
I know there is a junction, but from there I just can't set up any loops which would make any sense.
Thank you for your help.

Anyone? Just give me a hint please?

Your R2 and R3 are in parallel replace them with a single equivalent resistor. Now draw somr loops,

No need to calculate the parallel combination of R2 & R3.

R2 and R3 are directly across the 18V source so just apply Ohms law to find the current through each of them.

As for the outer loop... write an equation using KVL. Everything is known except for the current so you can solve for that. Apply Ohms law to work out voltage across R1.
