Using elementary transformations, find the inverse of each of the matrices.


First of all we need to check whether the matrix is invertible or not. For that-

For the inverse of a matrix A to exist,


Determinant of A ≠ 0


Here A = (2)(2) – (1)(4) = 0


So the matrix is not invertible.


the inverse of the given matrix does not exist.
