\

The equation is,

\

$\"\"$

\

The matrices have the same dimensions and the corresponding elements are equal.

\

The equality can be written as a two linear equations

\

$\"\"$ Equation (1)

\

$\"\"$ Equation (2)

\

$\"\"$

\

Consider the second equation $\"\"$

\

$\"\"$ (Subtract 1 from each side).

\

$\"\"$ (Additive inverse property: $\"\"$ ). \ \

\

$\"\"$ (Subtract: $\"\"$ ).

\

$\"\"$ (Divide each side by 4).

\

$\"\"$ (Cancel common terms).

\

$\"\"$ (Divide: $\"\"$ ).

\

$\"\"$

\

The first equation is $\"\"$

\

$\"\"$ (Substitute x = 3 in first equation)

\

$\"\"$ (Subtract 3 from each side).

\

$\"\"$ (Additive inverse property: 3 - 3 = 0). \ \

\

$\"\"$ (Subtract: $\"\"$ ).

\

$\"\"$ (Divide each side by 2).

\

$\"\"$ (Cancel common terms).

\

$\"\"$ (Divide: $\"\"$ ).

\

$\"\"$

\

The solution is $\"\"$ .
