x in (-oo:0) U (0:+oo)
(1/3)*x+5/x = (4*x)/3 // - (4*x)/3
(1/3)*x-((4*x)/3)+5/x = 0
(1/3)*x+(-4/3)*x+5/x = 0
5*x^-1-1*x^1 = 0
(5*x^0-1*x^2)/(x^1) = 0 // * x^2
x^1*(5*x^0-1*x^2) = 0
x^1
5-x^2 = 0
5-x^2 = 0
DELTA = 0^2-(-1*4*5)
DELTA = 20
DELTA > 0
x = (20^(1/2)+0)/(-1*2) or x = (0-20^(1/2))/(-1*2)
x = -5^(1/2) or x = 5^(1/2)
x in { -5^(1/2), 5^(1/2)}
