Not without knowing and seeing the values of ALL the variables used in the solve block.

If possible attach the Prime worksheet along with a pdf printout of the whole file for the helpers which can't read the Prime version you are using.

Chances are that the linear system you set up has no solution. Have you tried tracing back the error? Error messages of a solve block often are not telling you the true reason for the fail.

I found the problem. On the screenshot, the Vo=E/Ec but on the upper parts of the equation not seen on this screenshot, I wrote V0 instead of Vo. Thanks for the reply.
