8L=S
6L+2W=D
6L+1W=C
S+D+C=18
TO GET 118 LEGS & 20 PAIR OF WINGS WE NEED
5 SPIDERS+7 DRAGON FLIES+6 CICADA
5 SPIDERS HAVE 40 LEGS
7 DRAGONS HAVE 42 LEGS & 14 SETS OF WINGS
6 CICADA HAVE 36 LEGA & 6 SETS OF WINGS
------------------------------------------------------------
18 INSECTS HAVE 118 LEGS & 20 SETS OF WINGS (MAKE UP A TABLE WITH ALL THE DATA AND START FILLING IN THE BOXES)
