Answer 1

Show all work!

Answer 2

@Directrix

Answer 3

Do you know the properties in the word bank? I ask because this problem is not so much of a show your work problem as it is knowing and recognizing when the properties are being used.

Answer 4

Yup, I do!

Answer 5

How about this procedure?
You post what you got for the reasons and then I post what I got.
Where we differ, we can discuss that as showing work.

Answer 6

Alright,

Answer 7

@Ms-Brains I am ready when you are.

Answer 8

Want me to post the reason first, because I have them all.

Answer 9

Yes.

Answer 10

Mine:

1. Distributive
2. Commutative Prop
3. Additive Inverse
4. Identity Prop

Answer 11

I think we are in agreement.

Answer 12

Me too!
How about the other part though?

Answer 13

The statements?

Answer 14

The statements are given. We don't have to do anything with them other than to justify them with the reasons that they are true.

The statements are already logically arranged.

Answer 15

But what about the blank spot in the statments part, Isn't that part supposed to be filled?

Answer 16

What goes in each of those spots is -(x + y) + x

Answer 17

We are proving that:

-(x+y) + x = -y

So the left side stays the same.

The left side is being changed on the right side via the steps to show that it equals -y.
We provided the reasons.

Answer 18

Oh! Okay! Thanks! :)

Answer 19

>ut what about the blank spot in the statments part,

It is not really a blank spot.

It is an invisible -(x + y) + x

Somebody just didn't want to write it down on each line.

I don't know why.
