Answer: x=-1 and y= -3
Step-by-step explanation:
Solve for x, x+y=-4 
Minus y from both sides so it'll be X=-y-4 
Now substitute -y-4 in x-y=2 and solve for y
-y - 4 -y=2 
Add like terms, -2y - 4=2
Add 4 to both sides -2y=6
Divide both sides by -2  
 
y= -3
Substitute -3 in x=-y - 4
x=-(-3) - 4
- × (-3)= 3 
3 - 4= -1
x= -1
