Since lines \( m \) and \( n \) are parallel, the angles that are formed when a transversal intersects them are related. In this case, angles \( E \) and \( B \) are alternate interior angles, which means they are equal.
We can set up the equation:
\[ 3x + 18 = 14x - 8 \]
Now, we will solve for \( x \):
- Subtract \( 3x \) from both sides:
\[ 18 = 14x - 3x - 8 \]
- Combine like terms:
\[ 18 = 11x - 8 \]
- Add \( 8 \) to both sides:
\[ 18 + 8 = 11x \]
\[ 26 = 11x \]
- Divide both sides by \( 11 \):
\[ x = \frac{26}{11} \]
So the value of \( x \) is \( \frac{26}{11} \).
