Answer: [tex](-4, 3)[/tex]

Step-by-step explanation:

1) Add these equations to eliminate y: [tex]2x=-8[/tex]

2a) Then solve [tex]2x=-8[/tex] for x: [tex]2x=-8[/tex]

2b) Divide both sides by 2:  [tex]\frac{2x}{2} =\frac{-8}{2}[/tex]

2c) [tex]x=-4[/tex]

3) Substitute [tex]-4[/tex] for [tex]x[/tex] in [tex]x+y=-1[/tex]: [tex]-4+y=-1[/tex]

4) Simplify both sides of the equation: [tex]y-4=-1[/tex]

5) Add 4 to both sides: [tex]y-4+4=-1+4[/tex]

6) Simplify: [tex]y=3[/tex]

7) Write the point: [tex](-4, 3)[/tex]
