Answer:

(2, -4)

Explanation:

The solution to a system of equations is always going to be the point(s) where they intersect. To solve, use substitution and find each variable, x and y. Our final answer will be a set of coordinates (x, y). To plot this system, see the help image attached.

y = -x - 2

2x - y = 8

Substitute y to find x

2x - (-x - 2) = 8

2x + x + 2 = 8

3x = 6

x = 2

Substitute x to find y

y = -(2) - 2

y = -2 - 2

y = -4

Solution: (2, -4)

I hope this helps and God bless!
