Answer
The solution is between 3 and 4.
Work Step by Step
Create a table to approximate n. Since the difference is fractional, n must be fractional.
$\underline n\ \ \ \ \underline{3n-1}$
$1\ \ \ \ \ \ 2$
$2\ \ \ \ \ \ 5$
$3\ \ \ \ \ \ 8_\longrightarrow$ The solution is between 3 and 4.
$4\ \ \ \ \ \ 11$
