This C++/Python code implements the Gaussian elimination method to solve a system of linear equations.

1- The user specifies the number of unknowns (variables) in the system of linear equations.

2- The coefficients of the augmented matrix (including the right-hand side constants) are provided by the user.

1-The program transforms the augmented matrix into an upper triangular form using Gaussian elimination.

2- It starts by checking if the diagonal element (pivot) is zero. If so, it exits with an error message.

3- For each row below the current row, it calculates a ratio and subtracts a multiple of the current row from the subsequent rows to make the elements below the pivot zero.

1- After obtaining the upper triangular matrix, the program solves for the unknowns using back substitution.

2- Starting from the last row, it calculates the value of each unknown by subtracting the known values of the other variables.

1- The solution (values of the unknowns) is displayed after performing the calculations.
