Luacháil (complex solution)
x+y=13x+2y\text{ and }13x+2y=20
Réitigh do x.
x = -\frac{20}{11} = -1\frac{9}{11} \approx -1.818181818
y = \frac{240}{11} = 21\frac{9}{11} = 21.818181818181817
Réitigh do y.
y = \frac{240}{11} = 21\frac{9}{11} = 21.818181818181817
x = -\frac{20}{11} = -1\frac{9}{11} = -1.8181818181818181
