Mapel : Matematika
Kelas : X SMA
Bab : PLSV

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
