                 (Cancel common terms)        

                    (Multiply: )

(Multiply each side by negative one and flip the symbol)

                        (Product of two same signs is positive)

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 -59.15 and greater  than or equal to -59.15 in

          (Substitute: y = - 59.15)

                       (Divide: )

The inequality is true.
