To solve for \( x \), we can use the fact that angles formed by a transversal intersecting parallel lines have relationships that we can exploit. In this case, angle E and angle B can be considered alternate interior angles.

Given:
- Angle E = \( 3x + 18 \)
- Angle B = \( 14x - 8 \)

Since angles E and B are equal (because they are alternate interior angles), we can set up the equation:

\[
3x + 18 = 14x - 8
\]

Now, we will solve for \( x \):

1. Subtract \( 3x \) from both sides:
\[
18 = 14x - 3x - 8
\]
\[
18 = 11x - 8
\]

2. Add 8 to both sides:
\[
18 + 8 = 11x
\]
\[
26 = 11x
\]

3. Divide both sides by 11:
\[
x = \frac{26}{11}
\]

Thus, the value of \( x \) is \( \frac{26}{11} \).

The correct answer is:

\( \frac{26}{11} \)
