x+5 = 0
x+5 = 0
x+5 = 0 // - 5
x = -5
x+3 = 0
x+3 = 0
x+3 = 0 // - 3
x = -3
x in (-oo:-5) U (-5:-3) U (-3:+oo)
(x-5)/(x+5) = (x+5)/(x+3) // - (x+5)/(x+3)
(x-5)/(x+5)-((x+5)/(x+3)) = 0
(x-5)/(x+5)+(-1*(x+5))/(x+3) = 0
((x-5)*(x+3))/((x+5)*(x+3))+(-1*(x+5)^2)/((x+5)*(x+3)) = 0
(x-5)*(x+3)-1*(x+5)^2 = 0
-12*x-40 = 0
(-12*x-40)/((x+5)*(x+3)) = 0
(-12*x-40)/((x+5)*(x+3)) = 0 // * (x+5)*(x+3)
-12*x-40 = 0
-12*x-40 = 0 // + 40
-12*x = 40 // : -12
x = 40/(-12)
x = -10/3
x = -10/3
