Respuesta:
x=0 y= -2
Explicación paso a paso:
2y - 6x + 4 = 0 ------ 1
3y - 9x - 3 = 0 -------2
y = 0 + 6x - 4
2
Reemplazamos para hallar "x"
2( 6x-4) - 6x + 4 = 0
12x - 8 - 6x + 4 = 0
12x - 4 - 6x + 4 = 0
6x=0
x=0
Remplazamos "x" para hallar "y"
2y - 6(0) + 4 = 0
2y = -4
y = -2
Comprobamos:
2(-2) - 6(0) +4 = 0
-4 + 4 = 0
0 = 0
