## Homework Statement

Find v. A value for R is not needed. Circuit is attached.

## Homework Equations

KVL, KCL

## The Attempt at a Solution

I have no idea where to begin with this one. I found an answer using source transformations by transforming the 4A current source into a 12V voltage source in series and the 2A current source into an 8V voltage source in series.

At this point there's two loops, and I used KCL to find the current in the right loop to be 4A counterclockwise, and from there I used KVL in the supermesh loop to determine that v = -56V.

First of all, is this correct? Second, we haven't officially learned source transformations yet so I shouldn't be using them. I am clueless when it comes to current source behavior, so can someone explain to me how this would be done without source transformations?

Thanks!
