multiply both sides with (x-1) & 6...
6(x+1)=5(x-1)
6x+6=5x-5
6x-5x=-5-6
x=-11

x+1/x-1 = 5/6
x+1 = (5/6) x (x-1)
x+1 = 5(x-1)/6
6(x+1) = 5(x-1)
6x + 6 = 5x - 5
x = -11
Check:
(-11)+1/(-11)-1=-10/-12 = 5/6
Hope this helps! :-)

cross multiplying,
5(x -1) = 6(x +1)
5x -5 = 6x +6
x = -11

Cross Multiplying= times both sides by.
x+1/x-1=5/6
times both sides by x-1
x+1=5(x-1)/6
now times bothe sides by 6
6(x+1)=5(x-1)
6x+6=5x-5
therefor: x=-11
Like kodie had done check your answers
(-11)+1/(-11)-1=-10/-12 = 5/6
Correct so the value must be correct.

Write as:-
x + 1 / (x - 1) = 5 / 6
6x + 6 = 5x - 5
x = - 11

~~~
x+1/x-1 = 5/6 Cross multiplying
6(x+1) = 5(x-1)
6x + 6 = 5x - 5
6x - 5x = -5 -6
x = -11
~~~
