Sure, here are the steps to solve a system of linear equations using the Gauss-Jordan method:

1. Write the system of equations in augmented matrix form. This involves writing the coefficients of the variables and the constants in a matrix.

2. The goal is to transform this matrix into reduced row-echelon form. This is a form where the matrix has a diagonal of 1s from the top left to the bottom right, and zeros everywhere below and above the 1s.

3. Start with the first row. If the first element of the first row is not 1, divide the entire row by the value of the first element to make it 1.

4. Now, you want to make the rest of the elements in the first column zero. To do this, subtract multiples of the first row from the other rows such that the first element of each row becomes zero.

5. Move to the second row and second column. If the second element of the second row is not 1, divide the entire row by the value of the second element to make it 1.

6. Now, make the rest of the elements in the second column zero by subtracting multiples of the second row from the other rows.

7. Repeat this process for all the rows. In the end, you should have a matrix in reduced row-echelon form.

8. The solutions to the system of equations are the constants in the last column of the matrix.

Remember, when you are subtracting multiples of a row, you are essentially performing the operation on the corresponding equations. This method ensures that you are not changing the solution to the system of equations.
