5*x = 0
5*x = 0
5*x = 0
5*x = 0 // : 5
x = 0
x in (-oo:0) U (0:+oo)
13/(5*x)+2/3 = (3/5)*x // - (3/5)*x
13/(5*x)-((3/5)*x)+2/3 = 0
(-3/5)*x+13/(5*x)+2/3 = 0
13/5*x^-1-3/5*x^1+2/3*x^0 = 0
(2/3*x^1-3/5*x^2+13/5*x^0)/(x^1) = 0 // * x^2
x^1*(2/3*x^1-3/5*x^2+13/5*x^0) = 0

(-3/5)*x^2+(2/3)*x+13/5 = 0
(-3/5)*x^2+(2/3)*x+13/5 = 0
DELTA = (2/3)^2-(4*(-3/5)*(13/5))
DELTA = 1504/225
DELTA > 0
x = ((1504/225)^(1/2)-(2/3))/(2*(-3/5)) or x = (-(2/3)-(1504/225)^(1/2))/(2*(-3/5))
x = -5/6*((1504/225)^(1/2)-2/3) or x = 5/6*((1504/225)^(1/2)+2/3)
