The length of a rectangular playing feild is 5ft lessthan twice the width. If the perimeter of the playing field is 230ft, what is the length of the playing field.

x=length
y=width

we know:
2x+2y=230
x+5=2y

Solve using systems.

Easiest is to substitute x+5 for 2y into the first equation:

2x+x+5=230

then solve for x
