Respuesta :

if we add the 2 original equations

we will get

7x-3y=50

this is the second choice

first choice is not valid

third choice is incorrect, the equations are not equal

the forth choice is not valid

the fifth choice is correct,

if we have

5x+4y=24

and -(2x-7y=26)

we wil add them

5x+4y=24

-2x+7y=-26

we get 3x+11y=-2

second and fifth are correct, from the picture
