answer pls and show how did you get it thanks
2c + 4(c+3) = 24
HELP HELP HELP badly needed. . . .
is the solution like this?
2c+4c+12=24
6c=24-12
6c=12
c=12/6
c=2
Did I get it right steve?
Let's see if that answer works.
With 2 chickens, there must be 5 horses.
2 * 2 = 4 legs
5 * 4 = 20 legs
4 + 20 = 24 legs
Yep! Your answer is right!
Thank you. By the way I posted another question and posted my wrong answer can you please help me with that. Aprreciate it.

To find the number of chickens that John has, we need to set up a system of equations based on the information given.
Let's assume that John has x horses.
Since he has 3 less chickens than horses, the number of chickens he has would be x - 3.
Now, let's consider the total number of legs for the horses and chickens. Horses have 4 legs each, while chickens have 2 legs each.
The total number of legs for horses would be 4 * x = 4x.
The total number of legs for chickens would be 2 * (x - 3) = 2x - 6.
According to the problem, the sum of the total number of legs is 24.
So, we can set up the equation: 4x + 2x - 6 = 24.
Simplifying this equation gives: 6x - 6 = 24.
Adding 6 to both sides of the equation gives: 6x = 30.
Dividing both sides of the equation by 6 gives: x = 5.
Therefore, John has 5 horses. To find the number of chickens, we can substitute the value of x back into the equation x - 3.
So, John has 5 - 3 = 2 chickens.
Therefore, John has 2 chickens.
