---------------------------------------------------------- Combine like terms ---------------------------------------------------------- x - 6 = 6
---------------------------------------------------------- Add 6 to both sides ---------------------------------------------------------- x = 6 + 6 x = 12
---------------------------------------------------------- Substitute x = 12 into equation (1) ---------------------------------------------------------- y = 2 (12) + 6 y = 24 + 6 y = 30
---------------------------------------------------------- Answer : x = 12, y = 30 ----------------------------------------------------------
