Answer:
Spiders=8
Ants=12
Step-by-step explanation:
Spider(s)=8 legs
Ants(a)=6 legs
Total legs=136
Total heads=20
8s+6a=136 (1)
s+a=20 (2)
From (2)
s=20-a
Substitute 20-a into (1)
8s+6a=136
8(20-a)+6a=136
160-8a+6a=136
160-2a=136
-2a=136-160
-2a=-24
a= -24/-2
a=12
Substitute a=12 into (2)
s+a=20
s+12=20
s=20-12
s=8
