Answer:

Esta es mi respúesta dame Corona

Explanation:

1.

x+3y=4 (-4)

4x+5y=2

2.

-4x-12y=-16

4x+5y=2

3.

Se eliminan los Cuatros y restas las dos ecuaciones

-4x-12y=-16

4x+5y=2

4.

-4x-12y=-16

4x+5y=2

te da -7y=-14

y=-14/-7

Segundo Paso del ejercicio

1. remplazas y en una ecuacion

x+3y=4 en esta

4x+5y=2

2.

x+3y=4 x+3(-14/-7 )=4

3.

x+6=4 el 6 pasa al otro lado a restar

x=4-6

x=-2

Entonces esto seria el Fin.,
