    x = - 4

    Step-by-step explanation:

    Given

    3x - 2 (6 - x) = 7x + 2 (5 + x) - 6 ← distribute parenthesis on both sides

    3x - 12 + 2x = 7x + 10 + 2x - 6, that is

    5x - 12 = 9x + 4 (subtract 9x from both sides)

    - 4x - 12 = 4 (add 12 to both sides)

    - 4x = 16 (divide both sides by - 4)

    x = - 4 → A
