If you are talking about 340 = 2x + 2y, the problem won't be any different. Other than the fact that the variables are changed.

Hi,

The perimeter of a soccer field is 340m.

340=2l+2w

 170 = l + w

Let x and y represent the width and length repectively

 170 = y + x  OR y = -x + 170  All values > 0 for x and y

satisfying the EQ would work.
