(19/3)*x-1 = 6/x // - 6/x
(19/3)*x-(6/x)-1 = 0
(19/3)*x-6*x^-1-1 = 0
19/3*x^1-6*x^-1-1*x^0 = 0
(19/3*x^2-1*x^1-6*x^0)/(x^1) = 0 // * x^2
x^1*(19/3*x^2-1*x^1-6*x^0) = 0
x^1
(19/3)*x^2-x-6 = 0
(19/3)*x^2-x-6 = 0
DELTA = (-1)^2-(-6*4*(19/3))
DELTA = 153
DELTA > 0
x = (153^(1/2)+1)/(2*(19/3)) or x = (1-153^(1/2))/(2*(19/3))
x = 3/38*(3*17^(1/2)+1) or x = 3/38*(1-3*17^(1/2))
x in { 3/38*(1-3*17^(1/2)), 3/38*(3*17^(1/2)+1)}
x in { 3/38*(1-3*17^(1/2)), 3/38*(3*17^(1/2)+1) }
