Solution to Problem1


*****

Problem1:

Find the augmented matrix for the following system of linear equations

> ;

                      v + 2 w - y + z = 1

                          3 w + x - z = 2

                              x + 7 y = 1


SOLUTION:


Since there are 3 equations and 5 unknowns (v,w,x,y,z) the augmented matrix must be 3 rows and (5+1) columns. In maple,

> matrix(3,6,[1,2,0,-1,1,1, 0,3,1,0,-1,2, 0,0,1,7,0,1]);

                        [1    2    0    -1     1    1]
                        [                            ]
                        [0    3    1     0    -1    2]
                        [                            ]
                        [0    0    1     7     0    1]
