The inequality is .

Apply addition property of inequality: Add 3 to each side.

               (Additive inverse property: )

                     (Additive identity property: )

                            (Add: )

                        (Divide each side by 6)

                             (Cancel common terms)

                                  (Divide: )

Graph the solution set on a number line

Note: A dot means that this point is included in the solution set.

Check:

To check, substitute a number  7 or greater than or equal to 7, in .

                   (Substitute: h = 7)

                      (Multiply: )

                              (Substract: )

The inequality is true.

The inequality solution set is .
