1. Original Equation
2. Subtract 6u from both sides
3. Combining 16u-6u you get 10u
4. Subtract 4 from both sides
5. Combining -21-4=4
6. Dividing by 10
7. The total of -25/10=-2.5

Answer:
Area of walkway = 16(x+4) ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Step-by-step explanation:
Length of the sides of the square outdoor = x feet
Area of the square outdoor = length x length
= x * x
=
![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
The square outdoor is surrounded by 4 feet of walkway. So that,
length of the walkway = (x + 2(4))
= (x + 8)
Area of walkway with outdoor = (x + 8)*(x + 8)
= (
+ 16x + 64) ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Area of walkway = Area of walkway with outdoor - Area of the square outdoor
= (
+ 16x + 64) - ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
= 16x + 64
Area of walkway = 16(x+4) ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
