I'm sorry for the mistake.

I love Andras Horvath's solution. And I'm aware of the fact that there are other solutions to the puzzle. In fact, I've come up with one myself using a different approach. I wish I could view all the 7 solutions mentioned in the Mathcad website. However, I am unable to download and read those solutions in Mathcad format.

What I am now interested in is: how can the set of simultaneous equations be solved, if one is given only the equations, and that they are not linked to any specific problems.

Thank you for your comment.
