The equation is 

Replace z in with each value in the replacement set and

check whether the equation is true or not. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

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