Question

ayudaaa porfavorrr es método de reducción

Answer 1

Explicación paso a paso:

10x + 18y = - 11

2( 16x - 9y = - 5)

10x + 18y = - 11

32x - 18y = - 10

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

42x = - 21

x =. - 21/42

x = - 0,5

10x + 18y = - 11

10.(-0,5) + 18y = - 11

-5 + 18y = - 11

18y = - 11 + 5

18y = - 6

y = - 6/18

y = - 0,33
