Hi guys so when I do my calculations I get 20V for U can someone help me if I’m correct or not

If I interpret your somewhat unconventional drawing correctly, the answer is no.
To check: what is the current through R2?


Note that there is also a voltage source E=20V in series with the resistors, which makes it obvious that U can't be 20 V, too.
[Edit] Of course U could be 20 V, but not with the currents as shown.

when I do my calculations I get 20V for U

Show your calculations.

It could stand to have a little more clarity, but it's a cute little puzzle.
