Answer:
divide 16/20
Step-by-step explanation:
Answer: x= -1, y= -3
Step-by-step explanation
solve like a system of equations
x-y-2 = 0
+
x+y+4=0
------------
2x+2=0, 2x= -2, x= -1, then plug that back into either equation
-1+y+4=0, y+3=0, y= -3
(30/3-17/3)x(-2)+x=26/3
(13/3)x(-2)+x=26/3
-26/3+x=26/3
X=0
