## Homework Statement

Sorry for the quality of the image. This is the best I can come up with with my cellphone.

What is the current through the 10 ohms resistor?

Is the current from left to right or right to left?

## Homework Equations

Kirchhoff's loop law

Kirchhoff's junction law

## The Attempt at a Solution

1) I1 = I2 + I3 ==> I3 = I1 -I2

2) -5(I1) + 12V - 10(I2) + 3V = 0

15V = 10(I2) + 5(I1)

I1 = (15V - 10(I2))/5

3) -5(I3) + 9V + 3V + 10(I2) = 0

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

12V = -15 (I2) + 5 (I1)

= -15 (I2) + 15V - 10 (I2)

-3V = -25 (I2) ===> I2 = 0.12 A, from right to left.

This answer is incorrect. The correct answer is 0.36 A. Can someone please give me a hint as to what I'm doing wrong ?
