    Dear All,
    Please help on how to Compute for the unknowns (Vi and I2) on the attached picture, I really have a hard time on doing this. Please please help me.. Need this badly..

    The first two equations the supermesh currents and for mesh 1

    Thank you sir/mam, please help me solving the Vi and the I2

    Actually im stuck on the 3 current sources, I dont know the equation if thats the circuit, mam just the equations and I will do the rest (the substitution and elimination method). Thank you very much

    You will need a "constraint" equation for each current source. For the 20A source:

    I3 - I1 = 20 amps

    For the source common to I2 and I4:

    I2 - I4 = 2*I2

    Do you see how to form an equation for the source common to I4 and I5?

    You will also need an equation for the I2-I4-I5 supermesh.

    Also, you should indicate the polarity of the 150 volt battery.
