8/x+8 = (5/9)*x+5 // - (5/9)*x+5
8/x-((5/9)*x)-5+8 = 0
(-5/9)*x+8/x-5+8 = 0
8*x^-1-5/9*x^1+3*x^0 = 0
(3*x^1-5/9*x^2+8*x^0)/(x^1) = 0 // * x^2
x^1*(3*x^1-5/9*x^2+8*x^0) = 0
x^1
(-5/9)*x^2+3*x+8 = 0
(-5/9)*x^2+3*x+8 = 0
DELTA = 3^2-(4*8*(-5/9))
DELTA = 241/9
DELTA > 0
x = ((241/9)^(1/2)-3)/(2*(-5/9)) or x = (-(241/9)^(1/2)-3)/(2*(-5/9))
x = -9/10*((241/9)^(1/2)-3) or x = 9/10*((241/9)^(1/2)+3)
x in { -9/10*((241/9)^(1/2)-3), 9/10*((241/9)^(1/2)+3)}
x in { -9/10*((241/9)^(1/2)-3), 9/10*((241/9)^(1/2)+3) }
