x*z = -30
xz=−30x z = -30 
x + z = 38
x+z=38x + z = 38 
x + z = 38
Respuesta rápida
x1=19−391x_{1} = 19 - \sqrt{391}
=
19−39119 - \sqrt{391}
=
-0.773719933285189

z1=19+391z_{1} = 19 + \sqrt{391}
=
19+39119 + \sqrt{391}
=
38.7737199332852
x2=19+391x_{2} = 19 + \sqrt{391}
=
19+39119 + \sqrt{391}
=
38.7737199332852

z2=19−391z_{2} = 19 - \sqrt{391}
=
19−39119 - \sqrt{391}
=
-0.773719933285189
