Explanation / Answer

Let there be two loops with current I1 and I2

Now for loop1

9 + 5I1 + 10 (I1-I2) = 0

=> 15 I1 - 5 I2 = -9         (1)

loop 2

12 + 5 I2 + 10 (I2-I1) = 0

=> -10 I1 + 15 I2 = -12 (2)

SOlving the 2 eqns we got

I1 = -2.04 A          and I2 = -2.16A

current through 10 ohm i1-I2 = -2.04 -(- 2.16) = 0.12 A(ans)

In the direction of I2 = left to right.
