Ayuda

Answer 1

Respuesta:

$2x + 6y = 12\\10x - 4y = 26\\10 ( - 12 - 6y ) = 2 ( - 26 + 4y )\\- 120 - 60y = - 52 - 8y\\- 60y + 8y = -52 + 120\\- 52y = 68\\y = - 1.30769\\1ra e : 2x = 12 + 1.30769\\2x = 13.30769\\x = 13.30769 / 2\\x = 6.65384\\13.30769 - 1.30769 = 12\\2dae : 10x = 26 + 1.30769\\10x = 27.30769\\x = 27.30769 / 10\\x = 2.73076\\27.30769 - 1.30769 = 26$
