Equation 1: $\"\"$ , Equation 2: $\"\"$ . $\"\"$

\

Solve the equation 1: $\"\"$ .

\

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

\

$\"\"$ (Subtract 9 from each side)

\

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

\

Apply division property of equality: If a = b then $\"\"$ .

\

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

\

$\"\"$ (Cancel common terms and signs) $\"\"$

\

Solve the equation 2: $\"\"$ .

\

$\"\"$ (Subtract 12 from each side)

\

Rearrange the terms using commutative property addition: a + b = b + a.
