(

−4 1 4 4 −2 −3 −34+k 7 18

I know that a singular matrix is not invertible and has a determinant of zero. But what I am confused about is getting the above matrix into the form required. Do I have to do it in reverse from how we would calculate the determinant of a matrix? If so, how?

Thank you!
