             (Cancel common terms)

                (Divide: )

  (Multily each side by negitive one and flip the symbol)

                       (Product of two same signs is positive)

Graph the solution set on a number line. \ \ Note: A circle means that this point is not included in the solution set.

Check:

To check, substitute a number less than 12 in .

      (Substitute: x = 12)

          (Multiply: )
