9. 3x-6=4-2x

First, add 2x to both sides.

5x-6=4

Add 6 to both sides.

5x=10

Divide both sides by 5.

x=2

10. 3x+x=2x+6

Combine like terms.

4x=2x+6

Subtract 2x from both sides.

2x=6

Divide both sides by 2.

x=3

11. 6x=2+x+8

Combine like terms.

6x=10+x

Subtract x from both sides.

5x=10

Divide both sides by 5.

x=2

12. 6x+2-2x=x+8

Combine like terms.

4x+2=x+8

Subtract x from both sides.

3x+2=8

Subtract 2 from both sides.

3x=6

Divide both sides by 3.

x=2

I hope this helps :)

9) 3x-6 = 4-2x

add 6 to each side:

3x = 10-2x

Add 2x to each side:

5x = 10

Divide both sides by 5:

x = 10/5

x = 2


10) 3x +x = 2x +6

combine like terms on the left side:

4x = 2x +6

subtract 2x from each side:

2x = 6

Divide both sides by 2:

x = 6/2

x =3


11) 6x = 2 + x +8

Combine like terms on the right side:

6x = x +10

Subtract 1x from each side:

5x = 10

Divide both sides by 5:

x = 10/5

x = 2


12) 6x+2-2x = x +8

Combine like terms on the left side:

4x +2 = x +8

Subtract 2 from each side:

4x = x +6

Subtract 1x from each side:

3x = 6

Divide both sides by 3:

x = 6/3

x = 2

You know each side is 9 meters long, meaning it’s a square. To find perimeter, add up all the sides aka. 9+9+9+9=36. To find the area, multiply one side by the other aka. 9x9 = 81.
