The inequality is .

                      (Apply distributive property)

(Apply addition property of inequality:

For any real number, a, b, and c: If a < b then )

     (Add 48 to each side)

(Apply division property of inequality:

For any real number, a, b, and c: If a < b then )

                            (Divide each side by 32)

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

            (Product of two same signs is positive)
