• 7x + 8 = -7x

• 4 + 2x = 3 + 6x

• 4x + 2 = 3x + 6

What equation is shown in the model?

• -3x +14 = 4x

• 11x = 4x

• 17x = 4x

• 3x - 14 = 4x

What equation is shown in the model?

• 16x = 16x

• 7x + 9 = 2x +14

• 2x + 3 = 10

The model represents the equation _______________.

*** Do not include spaces in your equation.***

Green boxes are equal to 1 and red boxes are equal to -1. Solve for x.

• 12 = 3x + 6

• 12 = 3x - 6

• -12 = 3x -6

• 12 = -3x -6

What is the equation and the solution for the given model?

• 3x-4=5

• 3-4x=5

• 3-4x=5

• 3x-4=5

What would be the first step to solving the equation being modeled? (green=x red = -1 blue = 1)

• -2x - 4= 10

• 2x - 4 = 10

• -2x -4= -10

• 2x + 4 = 10

Which model represents the equation 3x - 1 = -4?

• 
• 
• 
• 

Greens are positive and reds are negative. Solve for x.

• x + 9 = -8

• -x + 9 = -8

• x - 9 = -8

• x + 9 = 8
