<human>:  A farm has 5 less than 9 times the amount of hens as roosters. If there are 75 total chickens, how many hens are there?
<bot>: Define a variable ** Let x represent the number of roosters
How many hens are there? ** Number of hens:9x-5
Write an equation ** Total:9x-5+x=75
Combine like terms ** 10x-5=75
Add 5 to each side ** 10x=80
Divide by 10 ** x=<<8=8>>8
How many hens are there? ** Number of hens: 9(8)-5=67
#### 67
