Question

14x-11y=-29
-8x+13y=30

Answer 1

Respuesta:

y = 2 , x = -1/2

Explicación paso a paso:

x = (30 - 13y)/-8

 

(-29 + 11y)/14 = (30 - 13y)/-8

-8(-29 + 11y) = 14(30 - 13y)  

232 -88y = 420 - 182y

-88y + 182y = 420 - 232

94y = 188

y = 188/94=2

x = (-29 + 11y)/14

x = (-29 + 11·2)/14

x = (-29 + 22)/14

x = -7/14 = -1/2
