The equation is, \ \

Using distributive property : .

        (Multiply the factors)

                          (Subtract:, )

Subtraction property of equality: If a = b then a - c = b - c

              (Subtract 3 from both sides)

                         (Additive inverse property: a + (-a) = -a + a = 0 ) \ \

                               (Subtract:)

                          (Divide both sides by )

                                  (Cancel common terms) \ \

                                    (Divide:)
