What are your thoughts on the second question?

dbzfan836 · Answer

i was thinking d

dbzfan836 · Answer

due to it being related to subtraction, the same thing that was removed

kropot72 · Answer

Considering D, specifically what subtraction can you see?

dbzfan836 · Answer

-7 is removed in all of the changes, and i acknowledge that d is meant to sometin=mes remove subtraction. and there is my logic

dbzfan836 · Answer

ps when i said d i meat D and I messed up Sometimes

kropot72 · Answer

So what is the correct operation to remove -7 from the left hand side of the original equation. Keep in mind that whatever operation you do to the left hand side you must also do to the right hand side, to maintain equality.

dbzfan836 · Answer

that is very true

dbzfan836 · Answer

yet I do not see where the left side changed

dbzfan836 · Answer

I mean right side

dbzfan836 · Answer

besides a different answer

dbzfan836 · Answer

so is it the addition equality, you are saying?

kropot72 · Answer

What is the result if you add 7 to the left hand side and to the right hand side?

dbzfan836 · Answer

you add, so it means the addition property is the answer, or B

dbzfan836 · Answer

I think we have a friend over, a moderator!

dbzfan836 · Answer

hello, picture-less mod!

kropot72 · Answer

Can you write the result if 7 is added to both sides of the original equation?

dbzfan836 · Answer

that would mean that the right side would be 12, not -2, crossing out D and A

kropot72 · Answer

And what would happen to the left hand side?

dbzfan836 · Answer

it would remove the -7

kropot72 · Answer

Correct. So you have confirmed that B is the correct choice.
