Okay we know that the total fence is 300ft. We don't know the sides, so we will use the variable x.
The front fence is twice as long as the side fence.
So the side fence is x and the front fence is 2x.
2x + x = 300ft (given)
3x = 300ft (combine like terms)
3x/3 = 300ft/3 (divide to simplify)
x = 100ft
