Find the current in the 2Ω resistor marked A

[fishy]

Homework Statement

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

Homework Equations

V=IR
Loop Rule
Junction Rule: I(in)=I(out(

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.

There are basically 3 sections to the circuit, the 8ohm-2ohm path on the left, the 8 ohm (which appears to be shorted)-2ohm-3ohm path on the right and the all the stuff in the middle.

What effect do the left and right sections have on the current through resistor A ?
