The question in a study book says to find the current through R2. I have very little experience dealing with dependent current and voltage sources, so I get thrown off when performing loop current (mesh) analysis. Here's the work so far, but the unknown of the voltage I1 makes too many unknowns.
I then attempted to do node analysis thinking that I could find the nodes between R2/R3 and R1/R2 then do a simple Ohm's calculation (Va-Vb/R2 = I2). I've searched the forums for similar questions, which there definitely are...but I'm not understanding how to do this since the current source is not expressed in terms of another branch current or some voltage coefficient.
I appreciate any help steering me in the right direction.
