Use elementary row operations to find the inverse of the matrix
[[1,1,1,9],[-11,-16,-9,-60],[1,2,1,3],[-2,-3,-1,-8]]or to show that it is not invertible. For full (or any) credit: show at least 4 of the row reduction stages in your work (including the last one), and list all of the row operations that you use to get from each stage to the next.
