Let s be the length of a section for plants.
Because opposite sides in a rectangle are equal we can state that 7 + 5s = 4 + 6s
Subtract 5s and 4 from both sides to get 7 - 4 = 6s - 5s which simplifies to 3 = s
The length of the wall = 7 + 5 x 3 = 22 ft
Check on opposite side: 4 + 6 x 3 = 22 ft
Start with
![-2x-4 < 3x+21](https://tex.z-dn.net/?f=%20-2x-4%20%3C%203x%2B21%20)
Add 2x to both sides:
![-4 < 5x+21](https://tex.z-dn.net/?f=%20-4%20%3C%205x%2B21%20)
Subtract 21 from both sides:
![-25 < 5x](https://tex.z-dn.net/?f=%20-25%20%3C%205x%20)
Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:
![-5 < x](https://tex.z-dn.net/?f=%20-5%20%3C%20x%20)
So, the answer is ![x > -5](https://tex.z-dn.net/?f=%20x%20%3E%20-5%20)
