Modeling One-Step Equations with Algebra Tiles

• -2x = 12

• 2x = 14

• x = 15

• 2x = 8

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

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

Which equation matches the image? THE RECTANGLES ARE THE VARIABLES & THE SQUARES EQUAL ONE EACH.

• x - 3 = 8

• x + 3 = 8

• 3x = 8

• 3x = 9

What do these Algebra Tiles represent?

• 2x = 8

• - 2x = - 8

• 3x = 12
