The replacement set is 

Replace k in  with each value in the replacement set

and check whether the equation is true. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\ k \	\        \	\        True or False \
\ 8 \	\   \	\            False \
\ 10 \	\   \	\            False \
\ 12 \	\   \	\            True \

\

 Since k = 12 makes the equation true, the solution of  is 12.
