2) a) Using matrix method solve the following simultaneous equations

2x + 3y = 13

       x – 4y = 1

1. Find the determinant of the following matrix

2      -1     -6

                  -3      0      5

                  4      3      0

1. c)  If told that matrix
   A
   is a singular Matrix find the possible value(s) for
   x
   

16

4x

                                A =
         x
