Hi

Im trying to copy my collegues work, he uses mathcad and I use maple. I have a problem when trying to solve a system of 7 equations and 7 unknows. For some reason he dosent seem to get the same problem of "Error, recursive assignment".

You can see a screen shot of his solution here:

And you can see my solution here:

As you can see the code dosent work, is there anyone that could help me understand why eactly this happens and how to fix this? 

Best Regards
