    I_1=I_2+I_3
    If in both mesh I go counterclockwise I get in the one on the right:
    24-7000I_1-4000I_2+18=0

    and the one on the left:

    4000I_2-2000I_3-20-18=0

    How can we possibly tell if what you have is correct since you don't define what I_1, I_2, or I_3 are?

    Good.

    Be sure to remember that voltage and current both have polarity, so when you indicate your currents be sure to indicate what direction is positive.
