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?

We are NOT mindreaders.

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.
