x*y = 1
$$x y = 1$$
y    
- = 2
x    
$$\frac{y}{x} = 2$$
y/x = 2
Respuesta rápida
$$x_{1} = - \frac{\sqrt{2}}{2}$$
=
$$- \frac{\sqrt{2}}{2}$$
=
-0.707106781186548

$$y_{1} = - \sqrt{2}$$
=
$$- \sqrt{2}$$
=
-1.4142135623731
$$x_{2} = \frac{\sqrt{2}}{2}$$
=
$$\frac{\sqrt{2}}{2}$$
=
0.707106781186548

$$y_{2} = \sqrt{2}$$
=
