Answer:
x=0
y= -1
Step-by-step explanation:
x−2y=2                 - eq 1
3x+2y=−2             - eq 2
x−2y=2
(3x+2y)+(x−2y)=−2+2
x−2y=2
3x+2y+x−2y=0
x=0
y= -1

Answer: B and C
Step-by-step explanation:
404 + 50 + 50 = 504
you are buying  144 magazines total
504/144 = cost of one magazine
cost of one = 3.50
you are paying $60 a year for 12 years
60 x 12 = 720
720/144 = 5
5 - 3.50 = 1.50
2. 
120x + 180x = 1080
300x = 1080
x = 1080/300
x = 3.6
3.6 x 60 = 216
