    6 - 2x - x = 18

    Simplify both sides of the equation.

    6 - 2x - x = 18

    6 + - 2x + - x = 18

    ( - 2x + - x) + (6) = 18

    - 3x + 6 = 18

    - 3x + 6 = 18

    Subtract 6 from both sides.

    - 3x + 6 - 6 = 18-6

    - 3x = 12

    Divide both sides by - 3.

    - 3x / - 3 = 12 / - 3

    x = - 4

    Answer:

    x = - 4
