Solution for z=(18/(z-7)) equation: 


D( z )

z-7 = 0

z-7 = 0

z-7 = 0

z-7 = 0 // + 7

z = 7

z in (-oo:7) U (7:+oo)

z = 18/(z-7) // - 18/(z-7)

z-(18/(z-7)) = 0

z-18*(z-7)^-1 = 0

z-18/(z-7) = 0

(z*(z-7))/(z-7)-18/(z-7) = 0

z*(z-7)-18 = 0

z^2-7*z-18 = 0

z^2-7*z-18 = 0

z^2-7*z-18 = 0

DELTA = (-7)^2-(-18*1*4)

DELTA = 121

DELTA > 0

z = (121^(1/2)+7)/(1*2) or z = (7-121^(1/2))/(1*2)

z = 9 or z = -2

(z+2)*(z-9) = 0

((z+2)*(z-9))/(z-7) = 0

((z+2)*(z-9))/(z-7) = 0 // * z-7

(z+2)*(z-9) = 0

( z+2 )

z+2 = 0 // - 2

z = -2

( z-9 )

z-9 = 0 // + 9

z = 9

z in { -2, 9 }
