x/(x+5)+2 = (3*x)/(x-5) // - (3*x)/(x-5)
x/(x+5)-((3*x)/(x-5))+2 = 0
x/(x+5)-3*x*(x-5)^-1+2 = 0
x/(x+5)+(-3*x)/(x-5)+2 = 0
(x*(x-5))/((x+5)*(x-5))+(-3*x*(x+5))/((x+5)*(x-5))+(2*(x+5)*(x-5))/((x+5)*(x-5)) = 0
x*(x-5)-3*x*(x+5)+2*(x+5)*(x-5) = 0
2*x^2-2*x^2-20*x-50 = 0
-20*x-50 = 0
(-20*x-50)/((x+5)*(x-5)) = 0
(-20*x-50)/((x+5)*(x-5)) = 0 // * (x+5)*(x-5)
-20*x-50 = 0
-20*x-50 = 0 // + 50
-20*x = 50 // : -20
x = 50/(-20)
