The solution is
Explanation:
I assumed that there is
Perform the Gauss Jordan elimination on the augmented matrix
Explanation:
I'll assume the middle equation was a typo and meant to be
First, begin by setting up the augmented matrix using the coefficients and constants from the 3 equations, For convenience reasons, I will actually make the 3rd equation my topmost equation in the matrix
Now, we use elementary row operations to try and reduce the left portion of the matrix to the identity matrix:
For readability I'll refer to an operation on Row n as
We can read the final answer in the right portion of the matrix:
Note If the original problem was not a typo, similar steps can be used to arrive at a different solution:
