The replacement set is z = .

Replace z in the equation with each value in the replacement set and check

whether the equation is true or not.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\ z \	\       \	\        True or False \
\ 10 \	\ \	\ False \
\ 12 \	\ \	\ True \
\ 14 \	\ \	\ False \
\ 16 \	\ \	\ False \
\ 18 \	\ \	\ False \

\

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

 The solution set is
