x*y = 1
xy=1x y = 1 
x = 2*y
x=2yx = 2 y 
x = 2*y
Respuesta rápida
x1=−2x_{1} = - \sqrt{2}
=
−2- \sqrt{2}
=
-1.4142135623731

y1=−22y_{1} = - \frac{\sqrt{2}}{2}
=
−22- \frac{\sqrt{2}}{2}
=
-0.707106781186548
x2=2x_{2} = \sqrt{2}
=
2\sqrt{2}
=
1.4142135623731

y2=22y_{2} = \frac{\sqrt{2}}{2}
=
22\frac{\sqrt{2}}{2}
=
0.707106781186548
