Respuesta:
x=-2
y=-3
Explicación paso a paso:
[tex]5x - 2y = - 4 \\ 3x + y = - 9[/tex]
[tex]y = - 9 - 3x[/tex]
[tex]5x - 2 \times ( - 9 - 3x) = - 4[/tex]
[tex]5x + 18 + 6x = - 4[/tex]
[tex]11x = - 4 - 18[/tex]
[tex]11x = - 22[/tex]
[tex]x = \frac{ - 22}{11} [/tex]
[tex]x = - 2[/tex]
[tex]y = - 9 - 3 \times ( - 2)[/tex]
[tex]y = - 9 + 6[/tex]
[tex]y = - 3[/tex]
