The system equations are

\

\"\"                            Equation (1)

\

\"\"                      Equation (2)

\

The matrix  equation form is \"\".

\

When, \"\".

\

Multiply each side by \"\".

\

\"\"

\

\"\"

\

\"\"

\

Therefore solution matrix is \"\".\"\"

\

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

\

\"\"

\

\"\"

\

\"\"

\

\"\".

\

Therefore A-1 exists.

\

\"\"

\

The inverse of A is \"\".

\

Substitute a = 5, b = 4, c = 4, d = \"\" and ad \"\" bc = \"\".

\

\"\".\"\"

\ Substitute the values of\"\" in the solution matrix \"\". \

Multiply each side by \"\".
