You may use a simple numeric solve block to do the job.

BTW, the way you tried to set up your matrices by matrix multiplication was awfully wrong! [3x3]*[3*1]=[3*1] and not a square matrix. You have to multiply by a diagonal matrix (see attached sheet).

Or you may define the matrix beforehand but then you must make it a function in all unknown variables:
