Question

x+1/x-1 - x-1/x+1= 48/7​

Answer 1

Step-by-step explanation:

x+1 x-1 48

----- - ----- = ----

x- 1 x+1 7

or, (x+1)(x-1) - (x-1)(x+1) 48

------------------------- = -----

(x-1)(x+1) 7

or, (x2 - x + x - 1) - (x2 + x - x - 1) 48

---------------------------------------- = --------

(x2 + x - x - 1) 7

or, (x2 - 1) - (x2 -1) 48

--------------------- = -------

(x - 1) 7

or, x2 - 1 - x2 + 1 48

------------------- = ------

x -1 7

or, 48x - 48 = 7

or, 48x = 7 + 48

or, 48x = 55

or, x = 55

------

48

or, x = 1.145834
