D( x )

x = 0

x = 0

x = 0

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

X-(5/x)-7 = 4/10 // - 4/10

X-(5/x)-(4/10)-7 = 0

X-5*x^-1-2/5-7 = 0

-5*x^-1 = -(X-37/5) // : -5

x^-1 = (37/5-X)/(-5)

-1 < 0

1/(x^1) = (37/5-X)/(-5) // * x^1

1 = x^1*((37/5-X)/(-5)) // : (37/5-X)/(-5)

-5*(37/5-X)^-1 = x^1

x = -5*(37/5-X)^-1

x = -5*(37/5-X)^-1
