Solution for X-2/x-1=4 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

X-(2/x)-1 = 4 // - 4

X-(2/x)-4-1 = 0

X-2*x^-1-4-1 = 0

-2*x^-1 = -(X-5) // : -2

x^-1 = (5-X)/(-2)

-1 < 0

1/(x^1) = (5-X)/(-2) // * x^1

1 = x^1*((5-X)/(-2)) // : (5-X)/(-2)

-2*(5-X)^-1 = x^1

x = -2*(5-X)^-1

x = -2*(5-X)^-1
