Respuesta:
x = 6 y = -2
Explicación paso a paso:
Método de igualación:
-3x-y=-16 => x = -16 + y/-3
x-5y=16 => x = 16 +5y
-16 + y/-3 = 16 +5y
-16 + y = -48 - 15y
32 = -16y => y = -2 x = 6
Comprobación:
-3(6) - (-2) = -16 => -18 + 2 = -16 => -16 = -16
6 - 5(-2) = 16 => 6 + 10 = 16 => 16 = 16
RPTA: x = 6 y = -2
