2 answers:
Answer:
-3
Step-by-step 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
Step-by-step 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
