Respuesta:
Solucion: (2,3)
Explicación paso a paso:
Ecuacion 1: x - 2y = -4
Ecuacion 2: 3x + y =9
[3x + y = 9](2) = 6x + 2y = 18
x - 2y = -4
7x = 14
x = 14/7
x = 2
2 - 2y = -4
-2y = -4-2
-2y = -6
y = -6/-2
y = 3
Solucion del Sistema: (2,3)
Prueba:
3x + y = 9
3(2)+3 = 9
6 + 3 = 9
9 = 9
2 - 2(3) = -4
2 - 6 = -4
-4 = -4
Espero a verte ayudado
