Finding a solution to a set of linear algebraic equations in Mathcad with Kramer method

Finding a solution to a set of linear algebraic equations in Mathcad with Kramer method

In Mathcad Kramer method is in use for finding a solution to a set  n of linear algebraic equations with  n unknown variables, equation looks like  A*x =b, solution based on precomputation  of system determinants on condition that determinant  Kramer Method of matrix А has nonzero value. Method is based on Kramer formulas, which look like   Kramer Method  , where Kramer Method is the determinant of the matrix, which we got after we changed i-matrix column, i.e. coefficient column which determines the unknown variable Xi, into vector of absolute terms b in matrix  А  of the system. The example of a solution to a set of linear algebraic equations in Mathcad with Kramer method is shown in the programme listing.
