2*x + y = 4
2x+y=42 x + y = 4 
x*y + 2*x = -12
xy+2x=−12x y + 2 x = -12 
x*y + 2*x = -12

x1=32−332x_{1} = \frac{3}{2} - \frac{\sqrt{33}}{2}
=
32−332\frac{3}{2} - \frac{\sqrt{33}}{2}
=
-1.37228132326901

y1=1+33y_{1} = 1 + \sqrt{33}
=
1+331 + \sqrt{33}
=
6.74456264653803
x2=32+332x_{2} = \frac{3}{2} + \frac{\sqrt{33}}{2}
=
32+332\frac{3}{2} + \frac{\sqrt{33}}{2}
=
4.37228132326901

y2=1−33y_{2} = 1 - \sqrt{33}
=
1−331 - \sqrt{33}
=
-4.74456264653803
