Homework Statement

Find I$_{1}$ in the circuit

Homework Equations

The Attempt at a Solution

I$_{1}$ + 4 mA = 2 mA
I$_{1}$ = -2 mA

This problem looks to have 2 unknowns. You aren't given the current flowing through the resistor on the left between the 2mA and 12mA legs. I would think you would need to write 2 equations to solve for I1 and that unknown current, but I could be wrong.
