Answer:

x=3.33333

y=0.44444

Step-by-step explanation:

Would equal to

-8x-8y=24 -equation 1

16x+8y = -56 -equation 2 (because of multiplying both sides by 8)

=-24x=80 (minus-ing equation two by equation one, on all sides)

= 24x = -80 (switching around the signs)

x =3.3333

and...

y =0.4444
