Solution to Problem2


*****

Problem2:

Find the system of linear equations corresponding to the augmented matrix

> ;

                             [3     0    -2     5]
                             [                   ]
                             [7     1     4    -3]
                             [                   ]
                             [0    -2     1     7]


SOLUTION:


This is a 3 by 4 matrix so it corresponds to a system with 3 equtaions in 3 unknowns (x,y,z) say. Using the matrix we obtain the system,

> ;

                    3 x - 2 z = 5

                7 x + y + 4 z = -3

                     -2 y + z = 7
