"Im(\\frac{z+9}{z})= 0.......z = x+iy"


"Im (\\frac{x+iy+9}{x+iy}) =0"


"Im(1+ \\frac{9}{x+iy}) =0"


"Im(1+ \\frac{9}{x+iy}\\times \\frac{x-iy} {x-iy}) =0"


"Im(1+ \\frac{9\\times (x-iy)}{x^2+y^2}) =0"


"Im(1+\\frac {9x-9iy} {x^2+y^2}) =0"


"\\frac{-9y}{x^2+y^2} = 0"

"y=0, z=x=Re(z)"

Answer :

"z=x=Re(z)"
