    2(3x - 6) / ((x - 1) (x + 1)) = 4/(x - 1) - 1/(x + 1)
    (6x - 12) / ((x - 1) (x + 1)) = (4 (x + 1) - (x - 1)) / ((x - 1) (x + 1))
    6x - 12 = 4x + 4 - x + 1
    6x - 3x = 12 + 5
    3x = 17
    x = 17/3
    x = 5 2/3

    Pembahasan :
    [2(3x - 6)]/(x - 1)(x + 1) + 1/(x + 1) = 4/(x - 1)
    (6x - 12)/(x - 1)(x + 1) + 1/(x + 1) = 4/(x - 1)
    (6x - 12 + x - 1)/(x + 1)(x - 1) = 4/(x - 1)
    (7x - 13)/(x + 1)(x - 1) = 4/(x - 1)
    (7x - 13)/(x + 1) = 4
    7x - 13 = 4x + 4
    7x - 4x = 4 + 13
    3x = 17
    x = 17/3
    x = 5 2/3

    Jawaban : E
