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

<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.

What is the value of x in the equation x – y = 30, when y = 15?
erastovalidia [21]

 x – y = 30, when y = 15

Then plug in the value

x - 15 = 30

Add 15 to both sides

x -15 + 15 = 30 + 15

Simplify:

x = 45
