The inequality is .

(Apply distributive property: a (b c) = ab ac)

          (Multiply: )

                 (Multiply: )

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

                       (Subtract:  )

Apply addition property of inequality: Add 16 to each side.

                 (Apply additive inverse property: )

                       (Apply additive identity property: )

                               (Add: )

Apply subtraction property of inequality: Subtract 2x from each side.

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

                         (Apply additive inverse property: )

                               (Apply additive identity property: )

                                         (Subtract: )

Check:

To check, substitute three different values for x into the original inequality: 8, a number less than 8, and greater than 8.

Let three values are .

If then       (This is false)

If then       (This is true)

If then (This is true).

The inequality solution set is  .
