Step 1: Assign current directions and label loops.
Let's assume the following current directions:
$I_1$: Current flowing upwards through the left branch (through $E_1$ and $R_1$).
$I_2$: Current flowing upwards through the middle branch (through $E_2$ and $R_2$).
$I_3$: Current flowing downwards through the right branch (through $R_3$).
Let's label the top junction as A and the bottom junction as B.
Step 2: Apply Kirchhoff's Current Law (KCL) at junction A.
At junction A, currents $I_1$ and $I_2$ flow into the junction, and $I_3$
