BartSMP [9]4 years ago
5 0
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
