Answer 1

$\huge\red{\underline{\underline{\underline{\underline{\boxed{\mathbb\purple{RESPUESTA}}}}}}}$

24x + 30y = 840

x + y = 39

METODO SUMA Y RESTA

24x + 30y = 840

x + y = 39

——————————

–24x–30y = –840

24x+24y = 936

——————————

–6y = 96

——————————

y = 96/–6

y = –16

——————————

x + y = 39

x –16 = 39

x = 36+16

x = 55

RESPUESTAS

y = –16 x = 55
