Answer
The solution is between 12 and 13.
Work Step by Step
Create a table with values of m and the corresponding values of the equation. Look for a 24 in the second column to find the value of m that is a solution.
$\underline{\ m\ }\ \ \ \underline{3m-13}$
$\ 10\ \ \ \ \ \ \ \ 17$
$\ 11\ \ \ \ \ \ \ \ 20$
$\ 12\ \ \ \ \ \ \ \ 23_{\longrightarrow}$ The solution is between 12 and 13.
$\ 13\ \ \ \ \ \ \ \ 26$
