D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
X-(2/x) = 47/7 // - 47/7
X-(2/x)-(47/7) = 0
X-2*x^-1-47/7 = 0
-2*x^-1 = -(X-47/7) // : -2
x^-1 = (47/7-X)/(-2)
-1 < 0
1/(x^1) = (47/7-X)/(-2) // * x^1
1 = x^1*((47/7-X)/(-2)) // : (47/7-X)/(-2)
-2*(47/7-X)^-1 = x^1
x = -2*(47/7-X)^-1
x = -2*(47/7-X)^-1
