Explanation / Answer

here,

using KVL in the upper loop

(r1 + R2 ) * I2 + R1 * I1 = E1

(0.5 + 2.5) * I2 + 6 * I1 = 19 ...(1)

and

using KVL in the lower loop

(r2 + R3) * I3 + R1 * I1 = E2

(0.5 + 1.5) * I3 + 6 * I1 = 41.5 ...(2)

and

using KCL

I1 = I2 + I3 ....(3)

from (1),(2) and (3)

I1 = 4.51 A

I2 = - 2.7 A

I3 = 7.2 A
