The inequality is .

      (Distributive property:)


           (Commutative property:)


Apply subtraction property of inequality:Subtract 8 from each side.

     (Commutative property:) 

               (Additive inverse property: )

                 (Subtract: )

       (Divide each side by 2)

               (Cancel common terms)


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

                           (Product of two same signs is positive sign)

 Graph the solution set on a number line

number line diagram inequality_x_greater_than_8

Note: A circle means that this point is not included in the solution set.


To Check, substitute a number greater than 8 in

      (Substitute )

         (Distributive property:)


                       (Additive inverse property: )

                              (Additive inverse property: )

The inequality is true.

The inequality solution set is .
