$\"\"$

The replacement set is $\"\"$

Replace m in $\"\"$ with each value in the replacement set

and check whether the equation is true. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \
\
m
\ \
       $\"\"$
\ \
       True or False
\
\
7
\ $\"\"$ \
           False
\
\
8
\ $\"\"$ \
           False
\
\
9
\ $\"\"$ \
           True
\
\

Since m = 9 makes the equation true, the solution of $\"\"$ is 9. $\"\"$

The solution set is $\"\"$ .
