ayudaa porfavorrr es método de reducción

Answer 1

Respuesta:

x = -1/2

y = -1/3

Explicación paso a paso:

2 ( 16x - 9y = -5 )

32x - 18y = - 10 +

10x + 18y = -11

---------------------

( 32x + 10x ) + 18y - 18y = -11 - 10

42x + 0y = -21

x = -21/42

x = -1/2

----

10(-1/2) + 18y = -11

18y - 5 = -11

18y = -11 + 5

18y = -6

y = -1/3

-----

Comprobación :

16(-1/2) - 9(-1/3)

-8 + 3 = -5
