<br>See attached file.
<br>At junction B, by KCL (Kirchhoff's current law):
<br>sum(Ii) = 0 => I1+I2 - I3 = 0
<br>=> I3 = I1 + I2 .... (1)
<br>For closed loop ABEFA, by KVL (Kirchhoff's voltage law):
<br>sum(Ii*Ri) = sum(Ei) (take clockwise as +ve direction):
<br>I3*R4 + I1*R1 = E1 ..........(2)
<br>For closed ...
