Step 1:
\Find the voltage across the nodes A and B.
\The current flowing through the first loop :
\Apply KVL to the first loop.
\The current flowing through the second loop :
\Apply KVL to the second loop.
\Step 2:
\The voltage across the nodes A and B.
\The voltage across the nodes A and B is -3.7 V.
\Solution : \ \
\\
The voltage across the nodes A and B is -3.7 V.
