Answer:
Equations: 
number of chickens = 52
number of goats = 28
Step-by-step explanation:
Given: A small ranch has chickens and goats
Total number of heads = 80
Total number of legs = 216
To find: number of chickens and goats
To draw: the graph
Solution:
Let x denotes number of chickens and y denotes number of goats.
According to the question,
From (i), put 
in (ii)
Put 
in equation (i)
So,
number of chickens = 52
number of goats = 28
First multiply (3x-7) and (2x+5)
i already did the multiplication so i am writing the answer
(3x-7)(2x+5)
6x^2+x-35
a is 6
b is 1
c is -35
if you want me to share how i did the multiplication then do let me know
85 + 51 = 136 passengers
136 passengers 51 passengers
