\

The matrix is $\"\"$ .

\

Rewrite matrix is A = $\"\"$ .

\

First find the determinant of A = ad $\"\"$ bc.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

Therefore A^-1 exists.

\

$\"\"$

\

The inverse of A is $\"\"$ .

\

Substitute $\"\"$ , $\"\"$ , $\"\"$ , $\"\"$ and ad $\"\"$ bc = $\"\"$ .

\

$\"\"$

\

$\"\"$ $\"\"$

\

CHECK:-

\

Find the product of the matrices.if the product is I, then they are inverses.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

The solution is true.

\

$\"\"$ The inverse matrix is $\"\"$ .
