= width of the walk (in feet)
= width of pool + walk (in feet)
= length of pool + walk (in feet)
area of pool = (in square feet)
area of pool + walk = (in square feet)
area of the walk = (in square feet)
Our equation is
Simplifying:
Since only a positive solution makes sense
-->
The walkway is feet wide.
