How to use
To solve the system Ax = b, first key in the number of equations
into the cell C4.
Then key in the matrix A into the yellow cells and b into the blue cells.
The solution x is obtained in column X, it is highlighted in green.
This screenshot shows the entries and solution for the following system:
2x1 + 3x2 + 3x3 = 1
2x1 + 3x2 + 2x3 = 1
3x1 + 3x2 + 3x3 = 3
The solution obtained is x1 = 2, x2 = -1 and x3 = 0.
