The inequality is .

Case 1: If a > b Then

Case 2: If a > b Then

Multiply each side by negative one and flip the symbol.

                  (Product of two same signs is positive)

Solve inequality for case 1.

Apply subtraction property of inequality: Subtract 2 from each side.

               (Apply additive inverse property: )

                     (Subtract: )

Solve inequality for case 2.

Apply subtraction property of inequality: Subtract 2 from each side.

                        (Apply additive inverse property: )

Graph the solution set on a number line.

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

The solution set is .
