first off you can't solve these 2 eqautions that you have, because you have 3 unknowns and 2 equations. You need another equation.

I see you used a supermesh for mesh 2 and 3, however you don;t need it. That is a current controlled voltage source there. This is why you are missing one equation. It would be a different story if there was a current source there.

I can't open your file or get any of your links to work to see the Circuit Diagram.

They aren't linked correctly, so you have to copy and paste it. Copy and paste the 3rd link and edit it to a basic URL.

my mistake, i looked at your work briefly and just saw the two numbered eqautions. I did the problem this time and get 79.2V. Your currents should be i1 = 3.08A i2=2.27A and i3=1.98
