Write the equation for the model. (white square=1 rectangle=x red square = -1)

• 7=x+3

• 7=x+(-3)

• 7=-x+3

• -7=x-3

Write the equation for the model.

• 7=x+3

• 7=x+(-3)

• 7=-x+3

• -7=x-3

Write an equation for the model above.

• x + 3 = -9

• x - 3 = 9

• 3x + 1 = 9

• 3x - 1 = 9

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

• 3x-4=5 x=1

• 3-4x=5 x=-2

• 3-4x=5 x=2

• 3x-4=5 x=3
