2/(x - 3) > 3/(x + 6)
2/(x - 3) - 3/(x + 6) > 0
(2 (x + 6) - 3 (x - 3))/((x - 3) (x + 6)) > 0
(2x + 12 - 3x + 9)/((x - 3) (x + 6)) > 0
(-x + 21) (x - 3) (x + 6) > 0
(x - 21) (x - 3) (x + 6) < 0
x - 21 = 0
x = 21

x - 3 = 0
x = 3

x + 6 = 0
x = -6

.. - .. -6 ... + .. 3 .. - .. 21 ... +

x < -6 atau 3 < x < 21
