Apply division property of inequality: Divide each side by 16.

               (Cancel common terms)

                    (Divide: )         (Multiply 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 in inequality .

     (Substitute )

                  (Multiply:)

The inequality is true. 

The inequality solution set is .
