Answer: x = 9, y = -14
Explanation:
4x + y = 16
2x + y = -2<span>
</span> 4x + y = 16
- 2x + y = -2
-------------------
2x + 0 = 18
-------------------
2x = 18
x = 9 <<<<< ¯\_(ツ)_/¯ For the value of x
Plug x = 9 into 2x + y = -2
2(9) + y = -2
12 + y = -2
y = -14 <<<<< ¯\_(ツ)_/¯ For the value of y

B isn't right, it isn't logical to just survey people with names starting with J or M. So, c would be just right since she's surveying 2 band members from each school so she would get information from a sample of the population and not just from her school.
