System of equations

I need a little help. Why isn't this working... How am I supposed to solve the system (except using a matrix without units or even this method but without units)

The problem is that Mathcad can't display a matrix or vector where the elements have different dimensions. This is exactly what your find command would force Mathcad to so (beta is of dimension length^-1, but the other elements are of dimension force*length^-1 (or mass*time^-2)).

The solution is not to evaluate the find command but to assign its results to a vector of variables which then can be displayed singly:

P.S.: Its not necessary to move the guesses to the top - I just did because I am used to
