1. The problem statement, all variables and given/known data 2. Relevant equations Loob Analysis V=IR 3. The attempt at a solution So I think I have the right equation here, but I am a bit confused on some parts. I am not too sure why i2=i1-ix. The way my professor explains it doesn't make much sense. Also (TYPO) in the second equation, the +2(i2) term should be 2(-i2) but I am not sure what the reasoning behind that is. This is my first time with loop analysis and it's not clicking yet, so could someone break down this equation bit by bit and explain it? The main part I am confused about is the branch in the middle with the 2ohm resistor and finding the current equation like i2=i1-ix. The rest makes sense.
