Practical Example

Let’s say you want to solve the system of equations:

x + 2y + 3z = 6
4x + 5y + 6z = 15
7x + 8y + 9z = 24

Steps:

1. Convert the equations into matrix form: [1,2,3;4,5,6;7,8,9]
2. Enter this into the Echelon Calculator and click Calculate.
3. The tool outputs:
   • Echelon Form: [1,2,3] | [0, -3, -6] | [0, 0, 0]
   • Rank: 2
   • Solution Type: Infinite solutions

This tells you the system does not have a unique solution and can guide you in further solving or analyzing it.
