The equation is $\"\"$ .

Apply multiplication property of equality: Multiply each side by $\"\"$ .

$\"\"$

$\"\"$ (Cancel common terms)

Apply division property of equality: Divide each side by a.

$\"\"$

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

Apply addition property of equality: Add 2 to each side

$\"\"$

Apply assosiative property of addition: a + (b + c) = (a + b) + c.
