Solve. x1 – 3x2 + 4x3 = -4 3xı – 7x2 + 7x3 = -8 –4x1 + 6x2 – x3 = 7

There is no solution for this system

Step-by-step explanation:

I am going to solve this system by the Gauss-Jordan elimination method.

The Gauss-Jordan elimination method is done by transforming the system's augmented matrix into reduced row-echelon form by means of row operations.

We have the following system:

This system has the following augmented matrix:

We start reducing the first row. So:

Now the matrix is:

We divide the second line by 2:

And we have the following matrix:

Now we do:

So we have

This reduced matrix means that we have:

Which is not possible
