Topic 1: Solving One & Two Step Equations

Multiple Choice

What is the inverse operation of addition?

• Division
• Multiplication
• Addition
• Subtraction

Multiple Choice

Solve for x.

• x = 50

• x = -12.5

• x = -50

• x = 12.5

Multiple Choice

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

Multiple Choice

-16+ x= -15

1st Step:

• Add 15

• Subtract 15

• Add 16

• Subtract 16

Multiple Choice

What do you need to do to both sides to isolate the variable?

• Add 5

• Subtract 5

• Multiply by 5

• Divide by 5.

Multiple Choice

How would you solve for x?

$$5x-1=19$$  

• Add 1, then divide by 5 on both sides
  
  $$x=4$$  

• Subtract 1, then divide by 5 on both sides
  
  $$x=10$$  

• Divide by 5, then add 1 on both sides
  
  $$x=5$$  

• Add 1, then multiply by 5 on both sides
  $$x=100$$  

Multiple Choice

Solve for x.

$$\frac{x}{5}+7=9$$  

• $$x=5$$  

• $$x=7$$  

• 
  
  $$x=9$$  

• 
  
  $$x=10$$  

Slide 9 Key

Subtract 7 on both sides (opposite of adding 7) Multiply by 5 on both sides (opposite of dividing by 5)

Multiple Choice

Solve for x.

$$-4x+3=-29$$  

• $$x=4$$  

• $$x=6$$  

• $$x=2$$  

• $$x=8$$  

Slide 11 Key

Subtract 3 on both sides (opposite of adding) Divide by -4 on both sides (opposite of multiplying)

Topic 2: Simplifying Expressions

Combining Like Terms & Distributive Property

Multiple Choice

Which of these are like terms in the following expression:
3x + 7 - 9x + 24y + 2x²

• 7, 24y
• 3x, 9x
• 3x, -9x
• 3x, -9x, 2x²

Multiple Choice

Simplify the following expression by combining like terms:

3 + 5x + 8 - 2x

• -3x² - 11

• 3x² + 11

• 11 - 3x

• 11 + 3x

Multiple Choice

Simplify by combining like terms: 7v + 2 + 12 + 2v

• 23
• 23v
• 9 + 14v
• 9v + 14

Multiple Choice

Simplify by combining like terms:
4x² - 3x + 11 -2x

• 4x² - 5x + 11
• 11x + 11
• 16x² - 5x + 11
• 10x²

Multiple Choice
