How many solutions does −2x+2y=-18

4.5 or 2×=-9

Step-by-step explanation:

I try my best

One: x = y + 9, and y = x - 9. Coordinate: (y + 9, x - 9)

Step-by-step explanation:

Let's solve for x.

−2x+2y=−18

Step 1: Add -2y to both sides.

−2x+2y+−2y=−18+−2y

−2x=−2y−18

Step 2: Divide both sides by -2.

−2x

−2

=

−2y−18

−2

x=y+9

Let's solve for y.

−2x+2y=−18

Step 1: Add 2x to both sides.

−2x+2y+2x=−18+2x

2y=2x−18

Step 2: Divide both sides by 2.

2y

2

=

2x−18

2

y=x−9

Hope this helps!
