Question 1186091
Instruction:  think of a number,<pre>
Response:  I think of x.</pre>
Instruction:  add 10<pre>
Response: I get x+10</pre>
Instruction:  and double the results.<pre>
 Response:  I get 2(x+10)</pre> 
Instruction: the answer is 28.<pre>  
Response: So my 2(x+10) equals 28. OK, so I write

                2(x+10) = 28</pre>  
Instruction:  Find the number<pre> 
Response:       I distribute the 2 on the left:

                2x+20 = 28

                I subtract 20 from both sides.

                   2x = 8

                I divide both sides by 2.

                    x = 4

                My answer is 4.</pre>
Instruction:  Congratulations!
