Question 1208737
.


Your setup in the post was incomplete, since the setup equation was not obtained.



As I see from this post and from many other your posts, your style of work is 
to do as few of the job as possible, by reloading the rest of the job to the shoulders of other (tutors).


And then "to make blue eyes" at the end.



Normally, you should make your job in full, from the beginning to the end, 
without reminding and elucidation from outside. It is what is expected from you.
