Which of the following represents the value of x?

What is the solution for this equation?

• x = 3

• x = 15

• x = 5

• x =1

An equation is modeled.

What is the value of x makes the equation true?

• 1

• 7

• -5

• -1

Which number line represents the solution(s) for the equation

• 
• 
• 
• 

Which model correctly represents the equation

4x + 108 = 144

• 
• 
• 
• 

Which equation matches the model?

• 6x + 3 = 12

• -3x - 6 = -12

• 3x + 6 = 12

• 6x - 3 = -12

Which equation matches the model?

• 3x - 2 = 5

• 2x - 3 = -5

• 3x + 2 = 5

• 2x + 3 = -5

What step could be used to solve for x?

• add negative 2 to both sides

• subtract negative 2 from both sides

• multiply by negative 2 on both sides

• divide by negative 2 on both sides

Which value of x makes the equation true?

• -2

• -1

• 1

• 2
