Hello!

To solve this system of equations I used the solve-block "Given-Minerr" (automatic algorithm):

P.S. What version of Mathcad are you using? I also recommend to you reading the following book by Brent Maxfield "Engineering with Mathcad": http://amzn.to/vko999

Am I missing something here, or is your middle equation wrong?

Your result does not match.

Illustration - 2<3 - no solution:

The case 1 |M| <> 0 - one solusion

The case 2 |M| = 0 - no solution (see above)

The case 3 |M| = 0 - a lot of solutions - see http://twt.mpei.ac.ru/ochkov/Mathcad_14/Chapter2/2_020_book.PNG
