"Algebraic Method" of solving linear equations using Matrices.
Consider the following system:
3x1 + 2x2 - x3 + x4 = -1
2x1 - x3 + 2x4 = 0
3x1 + x2 - 2x3 + 5x4 = -1
[ 3 2 -1 1 | -1 ]
[ 2 0 -1 2 | 0 ]
[ 3 1 2 5 | 2 ]
Coefficient Matrix :
[ 3 2 -1 1 ]
[ 2 0 -1 2 ]
[ 3 1 2 5 ]
Constant Matrix :
[ -1 ]
[ 0 ]
[ 2 ]
