Solution for (2x/x-1)-(7x/-3/x^2-1) equation: 


D( x )

x = 0

x^2 = 0

x = 0

x = 0

x^2 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

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

(2*x)/x-(((7*x)/(-3))/(x^2))-1+1 = 0

(7/3)*x^-1+(2*x)/x-1+1 = 0

7/3*x^-1 = -2 // : 7/3

x^-1 = -6/7

-1 < 0

1/(x^1) = -6/7 // * x^1

1 = -6/7*x^1 // : -6/7

-7/6 = x^1

x = -7/6

x = -7/6
