My solution is/was correct.



Then the tutor @MathTherapy came and brought his incorrect solution (see the same link).


Then @josgarithmetic came and brought the same incorrect solution.



My compassion to you, who can not distinct the correct solution from incorrect one. 



Regarding @josgarithmetic, keep in mind that his level is about "3" in 5 points student' scale (which is absolutely inappropriate for a tutor).


It means that he solves incorrectly every second - third - fourth standard/routine problem in the forum.


And solves incorrectly practically every non-standard problem.



But he always wants to present himself as an estime professor - academician.
