THe Farmer has 20 sheep and pigs. He has 6 fewer sheep than pigs. How many pigs does HE have?

13 pigs because then he would have seven sheep and 13-7=6.

26

To find out how many pigs the farmer has, we need to solve the problem step by step.

Let's call the number of pigs "P" and the number of sheep "S".
From the problem, we know that the farmer has a total of 20 sheep and pigs: S + P = 20.

We also know that the farmer has 6 fewer sheep than pigs: S = P - 6.

Now we can use substitution to solve the problem. We substitute P - 6 from the second equation into the first equation: (P - 6) + P = 20.

Simplifying the equation, we get: 2P - 6 = 20.
Add 6 to both sides of the equation: 2P = 26.
Divide both sides by 2: P = 13.

Therefore, the farmer has 13 pigs.
