I can't solve the problem using mesh current method.
I wrote 2 equations for the first and second mesh, but while there is a current source , I am wondering how to use it.
In the problem I was asked to find v0.

 

hi Ab,

My crystal ball is in the shop, so I can't begin to help you since I have no idea what two equations you wrote or even which two meshes are the "first and second mesh."

Perhaps if you showed your best attempt, however far you got, we might be able to help you get past your current roadblock so that you can continue.
