<h3><u>Answer:</u></h3>
- Option B is correct.
We know that:
- 2y + 2 = 3y - 9
- 3x + 6 = y + 4
Now, let's solve.
- => 2y + 2 = 3y - 9
- => 9 + 2 = 3y - 2y
- => y = 11
- => 3x + 6 = y + 4
- => 3x + 6 = 11 + 4
- => 3x = 15 - 6
- => 3x = 9
- => x = 3
Hence, Option B is correct.

Answer:
The length of the longest section x = 36 ft
Step-by-step explanation:
Total length of the wire = 51 ft
Let first section of wire = x
Second section of wire = y
Third section of wire = z
According to given data
x = 3 y & y = 4 z
Total length of the wire = x + y + z = 51
y = 12
x = 3 × 12 = 36
Therefore the length of the longest section x = 36 ft
