Answer:

-3

Explanation:

y = -2x+4y

It is given (_,-2), (x,y).

We must find the x coordinate.

Put y as -2.

(-2)= -2x+4(-2)

-2 = -2x+-8

2x = -8 + 2

2x = -6

2x/2 = -6/2

x = -3

Answer:

-3

Explanation:

1. Plug in -2 for y, because it is the y value in the coordinates

2. Simplify -2 = -2x + 4(-2)

3.That simplifies to -2 = -2x - 8

4. Add 8 to both sides to get 6 = -2x

5. Divide both sides by -2

6. x = -3
