3/x+2/x-1=4/x-1 tolong bantu saya tidak mengerti

3/x + 2/(x - 1) = 4/(x - 1)

3(x - 1) + 2(x) ... 4(x)
------------------ = ----------
......x(x - 1)............x(x- 1)

....3x - 3 + 2x - 4x
= ----------------------
.........x^2 - x
.....x - 3
= ----------
....x^2 - x

  3          2           4
----- + ------- = --------
  x       x - 1      x - 1  

  3         2           4
----- + ------- - -------- = 0
  x       x - 1     x - 1

   3(x - 1)            2x             4x
 ------------- + ----------- - ----------- = 0
   x(x - 1)        x(x - 1)     x(x - 1)

3x - 3 + 2x - 4x = 0

x - 3 = 0 ===> x = 3

semoga jelas dan membantu ya
