Question

8x + 8y = -64
16x - 8y = -32

ME AYUDAN PORFAVOR!!!

Answer 1

Respuesta:

8x + 8y = -64

16x - 8y = -32

24x = -96

x = -96/24

x = -4

reemplazas en "x"

8x + 8y = -64

8(-4) + 8y = -64

-32  + 8y = -64

8y = -64 +32

8y = -32

y = -32/8

y = -4

comprobación

8x + 8y = -64

8(-4) + 8(-4) = -64

-32 -32 = -64

-64 = -64

16x - 8y = -32

16(-4) - 8(-4) = -32

-64 + 32 = -32

-32 = -32
