The equation is .

Case 1: If a = b,Then

Case 2: If a = b, Then

                                   (Product of two same signs is positive)

Solve equation for case 1.

Apply subtraction property of equality: If a = b then a b = b a.

                     (Subtract 2 from each side)

                                 (Apply additive inverse property: )

                                    (Subtract: )

Apply division property of equality: If a = b then .

                                   (Cancel common terms)

                                         (Divide: )

Solve equation for case 2.

                        (Subtract 2 from each side)

                                    (Apply additive inverse property: )

                                          (Subtract: )

                                     (Divide each side by 5) \ \

                                          (Cancel common terms)

                                         (Divide: )

Graph the solution on a number line.

The equality solution set is {1.2 or 2}.
