Pre-Calc

Fencing is used to make a rectangular corral with length x feet and width y feet. Then more fencing is used to form a partition parallel to the length, splitting the corral into two pens of the same size. The total amount of fencing is 300 feet.
If the total amount of fencing is given by the equation 300 = 3x + 2y, solve this equation for y

I have to be honest I don't even know where to start with this problem. Any help would be appreciated

  1. Oh my, you are just solving a simple equation
    300 = 3x + 2y
    or
    2y + 3x = 300
    2y = 300 - 3x
    y = (300 - 3x)/2
    or
    y = 150 - (3/2)x

  2. Oh I was confused, I thought they were looking for a specific number for y.
    I'm just overthinking it I guess.
