Math Exam Resources/Courses/MATH152/April 2016/Question A 11 | 1 | 19:41, 26 March 2018 |

I have modified the solution in order to include the calculations showing how to solve the linear system. I would like someone to review this for readability. I am sure the answer is correct because Li and I got the same values.

Hey , Thanks for your work. I kind of doubt that a current can be negative since negative current does not make any sense. Here is some reference. http://www.math.ubc.ca/~elyse/152/2018/5Circuits.pdf

I am not familiar with circuit questions as well, so feel free to correct me if I am wrong.

Hi Aili,

Current actually can be negative depending on the direction the loop is pointing. I have verified that Li has correctly computed the values of and .

However, I have made some major changes to the structure of the solution, so I am putting it up for a second review.
