Answer:
x = 18
Step-by-step explanation:
1: 1/2x - 7 = 1/3x - 4
2: 3/6x - 7 = 2/6x - 4
3: 3/6x = 2/6x + 3
4: 1/6x = 3
5: x = 18
The answers are X=-4 and Y=3.

Answer:
The possible number of goats is 6 and the possible number of chicken is 24
Step-by-step explanation:
Let
chicken=c
Goat=g
the number of chickens could be four times the number of goats
c=4g
Total number of animals=30
c+g=30
Recall, c=4g
So,
c+g=30
4g+g=30
5g=30
Divide both sides by 5
5g/5=30/5
g=6
Recall,
c+g=30
c+6=30
c=30-6
=24
c=24
The possible number of goats is 6 and the possible number of chicken is 24 making a total of 30 animals
