**1. The problem statement, all variables and given/known data**

I attached the image, but it’s asking me to find the current in the 2Ω resistor marked A.

**2. Relevant equations**

V=IR

Loop Rule

Junction Rule: I(in)=I(out(

**3. The attempt at a solution**

I have no solution. I just conceptually don’t understand how my professor worked this problem and would like any guidance on what he did or some other way to complete this problem.
