Okay, here we have this:
We need to solve the following inequality, let's do it:
[tex]\begin{gathered} 3\mleft|5-y\mright|\le\: -6 \\ \mleft|5-y\mright|\le\: -2 \end{gathered}[/tex]
And considering that the absolute value cannot be less than zero, it means that the inequality has no solution in the set of reals.
