Using kirchoff's laws to solve a circuit
You should show your work to see how you have gone wrong.

An easy way to check if you are correct is to just plug the values into the circuit.

Itot = 12.69A

Edit
Your work just showed up. Your first loop should go all the way through the bottom area and not just on the left side.

Also the current in the circled resistor is just I3-I2.  All of your mesh current labels are off.  You have I3 written in as I2 in the top right ... but I2 is the mesh current on the left-top side. 

I fixed some problems with your graph.  Stop trying to force the other variables into loop currents which are not directly influencing them; just write the simple 3 equations first and then cancel variables.
