I'm trying to get UR5 from this schema, but something is not right.
I have a weakness that I need to redraw the circuit in a way that is easier to understand:
simulate this circuit – Schematic created using CircuitLab
R216 = R2+R1+R6 = 130 ohm
R21635 = R216 || R3 || R5 = 15.15 ohm
And the resistance of all the resistors combined is
R216354 = R21635 + R4 = 75.15 ohm
The current through all the resistors combined is
I = E1 / R216354 = 20 / 75.15 = 0.266 A
Since all of the current goes through R4, we can find U4
UR4 = I*R4 = 0.266 * 60 = 16.0 volts
UR5 = E1 - UR4 = 4 volts.
There is an arithmetic problem: -

So (R1+R2+R6) || R3 || R5 = 15.14563 Ω and not 15 Ω.
Then it's just a simple potential divider with the 15.14563 Ω and R4.
Hence, UR5 = 4.031 volts
