-11(x - 2) = 8
x - 2 = 8 + 11

Find the perimeter of the equilateral triangle.

Solve for x

Solve for b

Solve for v

Solve for x

Solve for n

-3(2x + 9) = 12 
2x + 9 = -4

Not Equal

18 = 3x - 6 + x 
18 = 4x - 6

Commutative Property

16 = 4(9 - x) 
16 = 36 - 4x

Division Property of Equality

5x = 20
4 - 5x = 24

Subtraction Property of Equality

5x = 4 + 2x 
3x = 24

Distributive Property

5x = 3 - x 
5x = -x + 3

The student is correct.

The student should have divided by 8.

The student is incorrect.

The student should have subtracted the 11.

The student should have divided by -11.

The student should have subtracted the 8.

The student should have added the two.
