In Exercises 7–26, use row reduction to find the inverses of the given matrices if they exist, and check your answers by multiplication. [**HinT:** See Example 2.]

To determine

**To calculate:** The inverse of the matrix

**Given Information:**

The provided matrix is

**Formula used:**

A matrix with *m* rows and *n* columns is of dimension *m* and *n* are positive integers.

Two matrices *A* and *B* are inverse pairs if *I* is the

To obtain inverse of a *A*, augment the matrix with

If the matrix obtained after row reduction has identity matrix on the left side then the matrix obtained on the right is the required inverse of *A* otherwise *A* is singular.

**Calculation:**

Consider the matrix

Since, number of rows in *m* and *n* in

Thus, dimension of

Augment the matrix with the

Thus, the augmented matrix is

Row reduce the matrix

Perform the row operation

Perform the row operation

Thus, row reduced form is
