This is a pretty simple question really and I'll feel embarrassed when I get the solution but its bugging me for now.
The goal is to solve for I going from left to right. No values given for any of the resistors. My instinct was to do mesh current and I came up with this solution.
I'm not using I2 at all and that's bugging me intuitively. The bottom part of the circuit is essentially being ignored and that doesn't seem right. Should I be doing I1 - I2? Is there a better approach to solving this?
