Hello everybody on the physics forum, i was just looking for someone to point me in the right direction and tell me if my equations are right

Homework Statement


Determine the current though the resistance R2 by mesh analysis
http://www.freeimagehosting.net/uploads/a77e95d378.jpg

The Attempt at a Solution


Ok, this is what i have so far:
Loop 1: I1=1A
Loop 2: R3(I2-I3)+R4(I2-I1)=12
Loop 3: -R1(I3-I1)+R3(I3-I2)-R2I3=0
