x  + 2*x - 4   x  + 5*x + 3           
------------ + ------------ <= 2*x - 1
   x + 3          x + 5               
$$\frac{\left(x^{2} + 5 x\right) + 3}{x + 5} + \frac{\left(x^{2} + 2 x\right) - 4}{x + 3} \leq 2 x - 1$$
(x^2 + 5*x + 3)/(x + 5) + (x^2 + 2*x - 4)/(x + 3) <= 2*x - 1

(-oo, -5) U (-3, -2]
$$x\ in\ \left(-\infty, -5\right) \cup \left(-3, -2\right]$$
x in Union(Interval.open(-oo, -5), Interval.Lopen(-3, -2))

Or(And(x <= -2, -3 < x), And(-oo < x, x < -5))
$$\left(x \leq -2 \wedge -3 < x\right) \vee \left(-\infty < x \wedge x < -5\right)$$
((x <= -2)∧(-3 < x))∨((-oo < x)∧(x < -5))
