Drag a reason to each box to complete this proof.If 12=13x+5 , then x = 21.

I think the answers are:

Statement          Reason  
12=13x+5          Given  
7=13x          Subtraction Property of Equality 
21 = x          Multiplication Property of Equality 
x = 21          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.
