Can anyone explain the following questions please:

1) For what value of k does the system of equations shown have no solution. (Use a matrix approach to the problem)

x + ky = 1

kx + y = 1

2) For which values of c does the system of equations shown have a solution? (This is best done using a matrix approach and you can use the internet to find the inverse of the 3 x 3 matrix to save some work if you want)

x - y - 3z = 3

2x . + z = 0

2y +7z = c

3) .

Thanks!
