Solving a system in terms of intersecting planes

In summary, the given problem is to find all solutions of a linear system with three equations and three variables. The equations are x + 4y + z = 0, 4x + 13y + 7z = 0, and 7x + 22y + 13z = 1. The attempted solution involves manipulating the equations to get a simplified system, but this leads to an inconsistent system with no solution. The problem asks to describe the solution in terms of intersecting planes.

Homework Statement



x + 4y + z = 0
4x + 13y + 7z = 0
7x + 22y + 13z = 1

Homework Equations


The Attempt at a Solution



x + 4y + z = 0
- 3y + 3z = 0
-6y + 6z = 1

x + 4y + z = 0
-y + z = 0
-6y + 6z = 1

Then whichever way I solve it I have 0=1 or 0=1/6, so where to go from here or is there just no solution?

First of all, the problem statement is NOT just
x + 4y + z = 0
4x + 13y + 7z = 0
7x + 22y + 13z = 1

That's not a "problem", that's a system of equations. What are asked to do with them?

Sorry I had only put it in the title of the thread.

Find all solutions of the linear system. Describe your solution in terms of intersecting planes.
 

What is a system of intersecting planes?

A system of intersecting planes is a set of two or more planes that have at least one point in common. This point is known as the point of intersection.

How can I solve a system of intersecting planes?

To solve a system of intersecting planes, you can use the method of substitution or elimination. In substitution, you solve for one variable in one equation and substitute the result into the other equation. In elimination, you manipulate the equations to eliminate one variable and solve for the other.

What is the importance of solving a system of intersecting planes?

Solving a system of intersecting planes is important in many areas of mathematics and science, such as in linear algebra, geometry, and physics. It allows us to find the point of intersection and determine the relationship between the planes.

Can a system of intersecting planes have more than one solution?

Yes, a system of intersecting planes can have infinite solutions if the planes are parallel or coincident. However, if the planes are not parallel, they will have exactly one point of intersection and only one solution.

What are some real-world applications of solving a system of intersecting planes?

Solving a system of intersecting planes can be applied in various fields, such as engineering, architecture, and navigation. For example, engineers use this concept to determine the intersection of beams in a building design, while pilots use it to calculate the intersection of flight paths.
