Question

Select the correct choice below and fill in any answer boxes in your choice

Answer 1

So we need to solve:

`(13)/(y)+(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} (13)/(y)+(5)/(y)=(1)/(y)(13+5)=3 \\ (13+5)/(y)=(18)/(y)=3 \end{gathered}`

Then:

`\begin{gathered} (18)/(y)=3 \\ 18=3y \\ (18)/(3)=y \\ y=(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 { }.
