Intro to Algebra Title

What equation do the algebra tiles show?

• -2x + 2 = x + 4

• 2x + 2 = x - 4

• 2x - 2 = -x + 4

• -2x - 2 = x + 4

Look at the model. Which of the following algebraic expressions could it represent?

• 3x + 4 + 2x + 1
• 7x + 3x
• 3x + 2x
• 4 + 1

Look at the model. Which of the following algebraic expressions could it represent?

• 5x - 1 + 2x + 3
• 5x + 5 +2x + 3
• 5x + 1 + 2 + 3
• 5x - 1 + 2x + 3x

What expression matches the model above?

• -x+2

• 3(-x+2)

• 3x+4

• 3(3x + 2)

Find the total amount of tiles.

• 7x + 6

• -10x - 5

• 10x + 1

• 10x + 5

Pick the equation modeled.

• 3x + 1 = x - 5

• -3x + 1 = x - 5

• 3x + 1 = x - 3

• 3x - 1 = x - 5

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

3x + 2(4x - 4) = 3

• 4
• 3
• 2
• 1

2x + 3(5x - 7) = 47

• 1
• 2
• 3
• 4

Solve.
(2x - 3) / 4  = 9

• x = 24
• x = 12
• x = 17.5
• x = 19.5
