\

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) $\"\"$

\

The first equation is $\"\"$ .

\

Apply subtraction property equality: If a = b, then $\"\"$ .

\

$\"\"$ (Subtract x from each side)

\

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

\

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

\

Apply division property of equality; if $\"\"$ , then $\"\"$ .

\

$\"\"$ (Divide each side by 3)

\

$\"\"$ (Cancel common terms)

\

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

\

The second equation is $\"\"$ .

\

According to addition property equality: if a = b, then $\"\"$ .

\

$\"\"$ (Add 1 to each side)

\

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

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

Apply division property of equality; if $\"\"$ , then $\"\"$ .

\

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

\

$\"\"$ (Cancel common terms)

\

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

\

The solution is $\"\"$ .
