A square wrestling mat has a perimeter of (12x-32) feet. Write an expression in simplest form that represents the side length (in feet) of the mat.

The equation is 12x-32=p. p is the perimeter. You would have to work backward and add 32 to p, making the equation now 12x=p+32. Now you have to divide it by 12, so the final expression is x=p+32/12 (x equals p plus 32 over 12)
