$\"\"$

The replacement set is $\"\"$

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

And check whether the equation is true. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \
\
p
\ \
       $\"\"$
\ \
       True or False
\
\
15
\ \
$\"\"$
\ \
           True
\
\
16
\ \
$\"\"$
\ \
           False
\
\
17
\ \
$\"\"$
\ \
           False
\
\ Since p = 15 makes the equation true, the solution of $\"\"$ is 15. $\"\"$

The solution set is $\"\"$ .
