Solution for 18/(x-2)+4=y equation: 


D( x )

x-2 = 0

x-2 = 0

x-2 = 0

x-2 = 0 // + 2

x = 2

x in (-oo:2) U (2:+oo)

18/(x-2)+4 = y // - y

18/(x-2)-y+4 = 0

18/(x-2)+(-y*(x-2))/(x-2)+(4*(x-2))/(x-2) = 0

4*(x-2)-y*(x-2)+18 = 0

4*x-(x*y)+2*y-8+18 = 0

4*x-(x*y)+2*y+10 = 0

(4*x-(x*y)+2*y+10)/(x-2) = 0

(4*x-(x*y)+2*y+10)/(x-2) = 0 // * x-2

4*x-(x*y)+2*y+10 = 0

4*x+2*y+10 = 0 // - 2*y+10

4*x = -(2*y+10) // : 4

x = (-(2*y+10))/4

x = (-(2*y+10))/4
