Solution for X-2/x=9/10 equation: 


D( x )

x = 0

x = 0

x = 0

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

X-(2/x) = 9/10 // - 9/10

X-(2/x)-(9/10) = 0

X-2*x^-1-9/10 = 0

-2*x^-1 = -(X-9/10) // : -2

x^-1 = (9/10-X)/(-2)

-1 < 0

1/(x^1) = (9/10-X)/(-2) // * x^1

1 = x^1*((9/10-X)/(-2)) // : (9/10-X)/(-2)

-2*(9/10-X)^-1 = x^1

x = -2*(9/10-X)^-1

x = -2*(9/10-X)^-1
