Solution for x=(x-54)/(x+2) 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)

x = (x-54)/(x+2) // - (x-54)/(x+2)

x-((x-54)/(x+2)) = 0

(-1*(x-54))/(x+2)+x = 0

(-1*(x-54))/(x+2)+(x*(x+2))/(x+2) = 0

x*(x+2)-1*(x-54) = 0

x^2+x+54 = 0

x^2+x+54 = 0

x^2+x+54 = 0

DELTA = 1^2-(1*4*54)

DELTA = -215

DELTA < 0

1 = 0

1/(x+2) = 0

1/(x+2) = 0 // * x+2

1 = 0

x belongs to the empty set
