The circuit looks like the one shown above.

The equivalent resistance of the parallel combination is\dfrac{1}{R'}=\dfrac{1}{12}+\dfrac{1}{6}+\dfrac{1}{4}
\implies R'=2\Omega

The current given out of the battery is\dfrac{20-8}{1+2+5+2}A=1.2A
Terminal potential difference across 20V battery=20-ir_1

Terminal potential difference across 8V battery=8+ir_2
