15/y+11-10/y+3=0
15/y-10/y=5/y 11+3=14
5/y+14=0
o-14=-14
5/y=-14
y=-5/14

Answer:
Walkway is 3 feet wide.
Step-by-step explanation:
Given:
Length of the building is 150 ft
width of the building is 100 ft
walkway is x ft wide.
Total area(around and including the building) = 16536 square feet
Solution:
Length of the total area will be = length of the building + width of walkway from 2 sides = 
Width of the total area will be = width of the building + width of walkway from 2 sides = 
Now Total area(around and including the building) = Length of the total area
Width of the total area


Now solving for both equation we get.

Now, We get 2 values for x which -128 and 3 but the width of the building can't be in negative value hence we will consider value of x be 3.
∴ Width of the walkway is 3 ft.
