What is the correct reason for statement 2 in the proof? (Posting the picture.) @_Michaeld22, Can you help me?

A. Identity property of addition B. Inverse property of addition C. Addition property of equality D. Multiplication property of equality @_Michaeld22, That's fine! Take your time.

OpenStudy (_michaeld22):

Okay, so it's definitely NOT D, as there is no multiplication involved in it. If I had to choose anything, it'd be C. Sorry if it's wrong, I'm just not good with proofs :(

OpenStudy (anonymous):

Yeah, I was thinking it would be C, too. Thank you for helping me again. :)

OpenStudy (_michaeld22):

Not a problem (:
