Question 829015
The description is slightly unclear, causing the trouble.


This is a try.

The number is n, (or any variable you want).
One-fourth of a number?  {{{(1/4)n}}};
One-fourth of a NUMBER DECREASED BY 5?   {{{(1/4)(n-5)}}}
Or is it this:
One-fourth of a number ----- Decreased by 5?  {{{(1/4)n-5}}}.
They are not the same, and the imprecise wording is the trouble.


The exercise author probably means the second one, (1/4)n-5, but still the description itself could use/needs some work.


This part, "...is -2", means  =-2
(Rendering will not work if the symbolic phrasing is an incomplete sentence)
