The given equation is .

Distribute terms using distributive property: a (b + c) = ab + ac.

                   (Product of two different signs is positive)

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

Combine like terms using distributive property: ab + ac = a (b + c).

                              (Add: 2 + 1 = 1)

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

            (Add 4w to each side)

                              (Apply additive inverse property: )

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

Combine like terms using distributive property: ab + ac = a (b + c).

                                         (Add: )

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

                             (Add 2 to each side)

                                         (Apply additive inverse property: )

                                               (Add: )

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

                                          (Divide each side by 3)

                                               (Cancel common terms)

                                                  (Divide: )
