For @josgarithmetic, it is &nbsp;&nbsp;<U>E X T R E M  E L Y  &nbsp;&nbsp;non-ethical</U>&nbsp;&nbsp; to place his answer after seeing my response.




&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As usual, &nbsp;his answer &nbsp;&nbsp;"x = 21" &nbsp;&nbsp;is &nbsp;&nbsp;<U>T O T A L L Y  &nbsp;&nbsp;W R O N G</U>.



==============
And my final address to the author of this post:


<pre>
    Usually those who post their problems correctly and in correct way,
    obtain very detailed answer, solution and explanations from me.


    Moreover, I often include references to my numerous lessons in this site to wider the students' knowledge.


    But not in this case.


    I am sensitive (as any other person) to the form of addressing to tutors (and to me personally),
    and can not tolerate addressing you used in this post.


    So, you lost a lot by neglecting commonly accepted communication rules.  
    Think about it and make right conclusions for future.
