$\"\"$ (Distribute 3)

\

$\"\"$ (Multiply: $\"\"$ ) $\"\"$

\

Apply addition property of equality: If a = b then a + c = b + c.

\

$\"\"$ (Add 5 to each side)

\

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

\

$\"\"$ (Apply additive identity property: $\"\"$ )

\

$\"\"$ (Add: 9 + 5 = 14) $\"\"$

\

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

\

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

\

Apply commutative property of addition: a + b = b + a.
