<span><span>I think the answers are:

Statement          Reason</span><span><span><span>  
<span>12=<span>13</span>x+5          </span></span>Given</span><span><span>  
<span>7=<span>13</span>x          </span></span>Subtraction Property of Equality</span><span><span> 
21 = x          </span>Multiplication Property of Equality</span><span><span> 
x = 21          </span><span>Symmetric Property of Equality 

By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not. 

Besides that, hope the answer above is correct for you.

Before you factor you should check what two things?
Sergeeva-Olga [200]

You can check your factoring by multiplying them all out to see if you get the original expression. If you do, your factoring is correct; otherwise, you might want to try again
