Modeling and Solving One Step Equations with Algebra Tiles

Write an equation to represent the tiles

• 3𝑥 + 2 = 3

• 2𝑥 = 3

• 5𝑥 = 3

• 3𝑥 − 2 = 3

What is the first step to solving this equation?

• add -8 to both sides

• subtract -8 to both sides

• Multiply -8 to both sides

• divide -8 to both sides

Which equation below represents the algebra tiles?

Write an equation to represent the tiles

• 3𝑥 + 4 = 4

• 4𝑥 − 3 = 4

• 3𝑥 = 4𝑥

• 4𝑥 + 3 = 4

• A

• B

• C

• D

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

What would be the next step?

• Take away the 6 positives on the left so that the variable is isolated.

• Bring in 6 negatives on the left.

• Move the 6 positives on the left, and place them on the right as negatives.

• Leave it alone

What do these Algebra Tiles represent?

• 2x + 4 = 12

• 2x - 4 = 12

• -4x + 7 = -32

• -2x - 5 = 12

What do these Algebra Tiles represent?

• -3x + 7 = 2x + 5

• 5x - 4 = 5x - 2

• -3x + 4 = 2x - 5

• 3x - 4 = 5x + 2
