Which step of justification is incorrect, and what should the justification for that step be to simplify the expression? Step 2; Commutative Property of Addition Step 3; Associative Property of Multiplication Step 4; Distributive Property Step 1; Multiplication Property of Equality

(Well you have to solve the problem in order to know what she did wrong) Look at the equation. From what you have learned, what do you have to do first?
anonymous
  • anonymous
actually scratch that, lets go through the steps of what she did
anonymous
  • anonymous
are you able to see the attachment?
anonymous
  • anonymous
I am able to see it
anonymous
  • anonymous
What was the first step she did? It was the distributive property, do you know how to do that?
anonymous
  • anonymous
I am now seeing these messgaes cuz openstudy is SLOW
anonymous
  • anonymous
nd yes I know how to do dist. property
anonymous
  • anonymous
Okay its fine, so did this girl do it correctly??
anonymous
  • anonymous
shouldn't it be 4 -( 5x-1)
anonymous
  • anonymous
No, thats not correct for this step. She has the distributive property correct
anonymous
  • anonymous
oh okay
anonymous
  • anonymous
So go to the next step. Does she have that correctly?
anonymous
  • anonymous
No
anonymous
  • anonymous
well I don't think so
anonymous
  • anonymous
correct she has that one wrong :) and thats your answer

Given: 3x + 1 = 2 + 2x – 4 Prove: x = –3 Given the equation 3x + 1 = 2 + 2x – 4, use the commutative property to rearrange the terms so that like terms are next to one another. This gives the equation 3x + 1 = 2 – 4 + 2x. Then use the associative property of addition to group the like terms. This gives the equation 3x + 1 = (2 – 4) + 2x. Next, combine like terms to get the equation 3x + 1 = – 2 + 2x. Use the subtraction property of equality to subtract 2x from both sides of the equation. This gives the equation x + 1 = – 2. Then use the _________________________ to subtract 1 from both sides of the equation. This gives the solution x = –3. Therefore, given the equation 3x + 1 = 2 + 2x – 4, x is equal to –3. Which justification was left out of the paragraph proof above?
