Question

Identify the solution(s) of the system of equations, if any. -2x - 2y = 4 8y = -8x - 16

Answer 1

$-2x - 2y = 4|:(-2)\\ 8y = -8x - 16|:(-8)\\\\ x+y=-2\\ -y=x+2\\\\ x+y=-2\\ x+y=-2\\\\ x,y\in \mathbb{R}$

Answer 2

-2x - 2y = 4|:(-2) 8y = -8x - 16|:(-8) 
x+y=-2 -y=x+2 x+y=-2x+y=-2 
Ansfwer  :  x-2 y -2
