Solution for 9/x=85/10y equation: 


D( x )

x = 0

x = 0

x = 0

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

9/x = (85/10)*y // - (85/10)*y

9/x-((85/10)*y) = 0

9/x+(-17/2)*y = 0

9*x^-1 = -(-17/2*y) // : 9

x^-1 = 17/18*y

-1 < 0

1/(x^1) = 17/18*y // * x^1

1 = 17/18*x^1*y // : 17/18*y

18/17*y^-1 = x^1

x = 18/17*y^-1

x = 18/17*y^-1
