The inequality  is .

                           (Product of two differnt signs is negative)

Apply addition property of inequality: If a < b then a + c < b + c.

          (Add 12 to each side)

                     (Apply additive inverse property: )

                           (Apply additive identity property: )

                                   (Add: )

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 solution, substitute a number greater than 37 in

                         (Substitute )

                                 (Subtract: )

The inequality is true

The inequality solution set is .
