Step 1:

\

The multiple matrix is $\"\"$ .

\

Find $\"\"$ value.

\

$\"\"$

\

Solve the equation.

\

$\"\"$

\

Step 2:

\

Check the solution for $\"\"$ -values.

\

Substitute $\"\"$ in the given matrix.

\

$\"\"$

\

Since, $\"\"$ does not satisfied the matrix.

\

Substitute $\"\"$ in the given matrix.

\

$\"\"$

\

$\"\"$ is satisfied the matrix.

\
