Gaussian Elimination and Row Echelon Form - Example 1
In todays video we are going to solve system of linear equations using gaussian elimination and row echelon.
To solve a system of equation, you represent the set of equations in a form of argumented matrix thus [A | b]
1. The elements in the leading diagonal should be 1
2. All elements under the leading diagonal should be 0
3. If a row is made up of all zeros, it should be placed at the buttom of the matrix.
After obtaining the row echelon form of the matrix, transform that back to a system of equations and find the unknown variables.
