Regarding this problem,  there is a dispute between two tutors,  @MathLover1  and  Edwin.

I will refer to the post

https://www.algebra.com/algebra/homework/Expressions-with-variables/Expressions-with-variables.faq.question.1180564.html

of yesterday,  where both tutors placed their solutions. 


    The current solution by @MathLover1 is the copy of her solution, 
    placed under the cited link.


I do not see any reason to repeat the mathematics of both participants.

I attentively looked at both solutions,  and I see that the solution and the answer by  Edwin  is  RIGHT,
while the answer and the solution by  @MathLover1 are incorrect  (have an error).


The error in the solution by  @MathLover1  is in the row number  12.


        It is not amazing to make an error by writing five-storey fractions.


        This style  ( writing multy-storey fractions with the number of stores more than  4 )  leads to errors   INEVITABLY.


////////////


Resume:   use the solution and the answer by  Edwin

and ignore the answer and the solution by  @MathLover1.
