Open the brackets ⇒ 5x − 15 = 2x + 12

Subtract 2x from both sides ⇒ 5x – 2x − 15 = 2x − 2x + 12

Tidy up                                  ⇒ 3x − 15 = 12

Add 15 to both sides            ⇒ 3x − 15 + 15 = 12 + 15

Tidy up                                  ⇒ 3x = 27

Divide both sides by 3          ⇒ 3x/3 =27/3 

                                              ⇒ x = 9
