BartSMP [9]

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
