Solution for 1/x-1+2=9/X-1 equation: 


D( x )

x = 0

x = 0

x = 0

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

1/x-1+2 = 9/X-1 // - 9/X-1

1/x-(9/X)-1+1+2 = 0

1/x-9*X^-1-1+1+2 = 0

1*x^-1 = -(2-9*X^-1) // : 1

x^-1 = -(2-9*X^-1)

-1 < 0

1/(x^1) = -(2-9*X^-1) // * x^1

1 = x^1*(-(2-9*X^-1)) // : -(2-9*X^-1)

-(2-9*X^-1)^-1 = x^1

x = -(2-9*X^-1)^-1

x = -(2-9*X^-1)^-1
