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?
Please answer and provide answer explanation.
67
Let x represent the number of roosters.

Number of hens:9x - 5.

Total:9x - 5 + x = 75.

10x - 5 = 75.

10x = 80.

x = 8.

Number of hens: 9(8) - 5 = 67.

.

So, the final answer is 67
