Samuel needs to solve the equation 4(x - 2) + 2 = 4x - 8.  

Which equations represent a first step Samuel could use to solve the original equation?

Select all that apply. 

• Samuel distributes 4 on the left side of the equation to get 4x - 8 + 2 = 4x - 8.
  

• Samuel distributes 2 on the left side of the equation to get 4(2x - 4) = 4x -- 8.

• Samuel divides both sides of the equation by 4 to get x - 2 + 2 = x - 2. 

• Samuel subtracts 2 from both sides of the equation to get 4(x - 2) = 4x - 10.

• Samuel subtracts 4 from both sides of the equation to get x - 2 + 2 = 4x - 12.

Irene is solving the equation 2x − 4(2x + 3) = 3(−x + 2) − 3 .

In her first step, she rewrites the equation as 2x − 8x − 12 = −3x − 6 − 3 . 

What error did Irene make, if any?

• Irene did not multiply/divide both sides correctly.

•  Irene did not add/subtract from both sides correctly.

•  Irene did not distribute correctly. 

  
  

• Irene did not make an error.
