So we need to solve:

$\frac{13}{y}+\frac{5}{y}=3$

First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:

$\begin{gathered} \frac{13}{y}+\frac{5}{y}=\frac{1}{y}(13+5)=3 \\ \frac{13+5}{y}=\frac{18}{y}=3 \end{gathered}$

Then:

$\begin{gathered} \frac{18}{y}=3 \\ 18=3y \\ \frac{18}{3}=y \\ y=\frac{18}{3}=6 \end{gathered}$

So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.
