**Problem:**

Given \( m \parallel n \), find the values of \( x \) and \( y \).

**Diagram Explanation:**

- The diagram shows two parallel lines \( m \) and \( n \) intersected by a transversal.
- One of the angles formed on line \( m \) by the transversal is labeled as \( (4x - 2)^\circ \).
- The corresponding angle on line \( n \) is labeled as \( y^\circ \).
- Another angle on line \( n \), adjacent to the angle \( y^\circ \), is labeled as \( (6x + 12)^\circ \).

**Solution Approach:**

1. **Corresponding Angles:**
   - Since lines \( m \) and \( n \) are parallel, the corresponding angles are equal. Therefore, \( (4x - 2)^\circ = y^\circ \).

2. **Linear Pair:**
   - Angles \( y^\circ \) and \( (6x + 12)^\circ \) are linear pairs, hence they sum up to \( 180^\circ \). Therefore, \( y + (6x + 12) = 180 \).

This setup allows us to solve the equations to find the values of \( x \) and \( y \).
