Answer:
x=-8
y=4
Step-by-step explanation:
first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16
3x+2y=-16
(x+9y=28)3 _multiply with 3
3x+2y=-16
3x+27y=84
use minus(-) =3x-3x=0
=2y-27y=-25y
=-16-84=-100
the result:-25y=-100
y=4
take any simple equation and replace y with 4
x+9y=28
x+9(4)=28
x+36=28
x=28-36
x=-8
answer:x=-8,y=4
The answer is b.) 120 degrees
