ANSWER

A) 4x - 7 = 21

EXPLANATION

We have that 21 goats were shown in the county fair.

The number of goats is 7 less than 4 times the number of horses.

Let the number of horses be h.

Therefore, 7 less than 4 times the number of horses is:

4 * x - 7

= 4x - 7

We have this is equal to the number of goats. Therefore, the equation that can be used to solve the problem is:

4x - 7 = 21
