    Im using the Mesh Current Method to find the voltage across R2 (5k). I dont know how to write the equation for Loop 3.


    I tried removing Loop 3 from the circuit then calculating the currents for loop 1 and loop 2, then putting back loop 3 (6 mA) back into the circuit - that didnt work.

    The current 6mA flows in R5 path, hence you can find the voltage across R5.
    The voltage across R5 = voltage across R2 since the two are parallel.

    The voltage across R5 does not equal the voltage across R2.

    The equation for the third loop is: I3 = -.006, assuming you take all the mesh currents to be clockwise.

    I converted the current source (6 mA) to its Thevenin equivalent which simplified the equations:)
