Start by adding 13 to both sides
19 = 4b-13
<span>19+13 = 4b-13+13
</span>32 = 4b
4b = 32
Then divide both sides by 4 to isolate b
4b = 32
4b/4 = 32/4
b = 8
So in the end, b = 8

<u>Answer</u>:
the length of chicken coop and the garden is of 40 feet.
<u>Explanation</u>:
Given that the garden is the length of the chicken coop, equal length
→ 3x + 12 = 6x – 16
→ 3x - 6x = -16 - 12
→ -3x = -28
→ 
→ 
→ x = 9.33 feet.
- The garden length = 3(
) + 12 → 40 feet - the chick coop length should be same as the garden length.
