Answer:
(-4, 3)

Step-by-step explanation:

1) Add these equations to eliminate y:
2x=-8

2a) Then solve
2x=-8 for x:
2x=-8

2b) Divide both sides by 2:
(2x)/(2) =(-8)/(2)

2c)
x=-4

3) Substitute
-4 for
x in
x+y=-1:
-4+y=-1

4) Simplify both sides of the equation:
y-4=-1

5) Add 4 to both sides:
y-4+4=-1+4

6) Simplify:
y=3

7) Write the point:
(-4, 3)
