**Question 28:**

Find a vector parallel to the line of intersection of the two planes \(4x - 3y + 2z = 12\) and \(x + 5y - z = 25\).

---

**Explanation for Educational Context:**

In this question, we are tasked with finding a vector that runs parallel to the line where two planes intersect. Each plane is described by its own linear equation in three-dimensional space:

- The first plane is represented by the equation \(4x - 3y + 2z = 12\).
- The second plane is described by the equation \(x + 5y - z = 25\).

The line of intersection of these two planes can be found by solving these simultaneous equations. Once we have the line, we can determine a vector that is parallel to it. 

This concept is common in linear algebra and vector calculus, where understanding intersections and vector directions can be applied in fields such as physics, engineering, and computer graphics.
