$y = \frac{4x-3}{2} \\ 2y=4x-3 \\ 4x=2y+3 \\ x= \frac{2y+3}{4} \\ f^{-1} (x)=\frac{2x+3}{4}$

In a pen of goats and chickens there are 25 heads and 90 feet. How many goats and chickens are in the pen.

Anna [14]

Answer:

5 chickens, 20 goats

Step-by-step explanation:

We can set up two equations and use substitution

There are 25 total goats and chickens, so

$G + C = 25$

Goats have 4 feet and chickens have two, so

$4G + 2C = 90\\$

By solving for G in the first equation,

$G = 25 - C\\$

We can now use substitution,

$G = 25 - C\\4G + 2C = 90\\4(25 - C) + 2C = 90\\100 - 4C + 2C = 90\\-2C = -10\\C = 5\\$

We have 5 chickens, so we have 20 goats.

Let's double check:

$5(2) + 20(4) = 90\\10 + 80 = 90\\90 = 90\\$

It checks out!
