Let x = width of pool, then x + 5 = length of pool

x+ 9 = length of walk, and x+4 = width of walk

Area of pool = x(x +5)

Area of walk and pool =(x + 9)(x + 4)

Area of pool + 156 = Area of walk and pool

x(x + 5) + 156 = (x + 9)(x + 4)

Now, solve the equation for x which wiki give you the width of the pool.
