Modeling and Solving One Step Equations with Algebra Tiles

Which equation below represents the algebra tiles?

What equation is modeled? Solve the equation.

• x -6 = 13

• x + 6 = 13

• x + 6 = 13

• x - 6 = 13

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

Solve the equation using the image. THE RECTANGLES ARE THE VARIABLES & THE SQUARES EQUAL ONE EACH.

• n = 14

• n = 6

• n = 7

• n = 2

If the triangle represents the variable and each circle equals one, is this model and equation in the image correct?

• Yes

• No, there needs to be 7 circles on the right side of the equal sign.

• No, there needs to be 4 circles on the right side of the equal sign.

• No, there needs to be a minus sign in the equation.

Write an equation for the model above.

• x + 3 = -9

• x - 3 = 9

• 3x + 1 = 9

• 3x - 1 = 9

What equation is modeled?

• 3 = 6

• 3x = 6

• x = 6

• 3 = 6x

What is the equation being modeled?

• 4x+3 = 5x

• 3x + 4 = 5

• 7x = 5

• 3x - 4 = 5

• -3x + 4 = 5

• 4x - 3 = 5

• -4x + 4 = 5

• 4 - 3 = 5

• -2x = 12

• 2x = 14

• x = 15

• 2x = 8
