Answer:
Step-by-step explanation:
The given systems of equations is
The augmented matrix is
.
We perform the following row operations to reduce the matrix to reduced row echelon form using row 1 as our pivot row.
Next, we perform the following row operations using row 2 as our pivot row to obtain,
Next, we perform the following row operations using row 3 as our pivot row to get,
The matrix is now in the reduced row echelon form,
Therefore the solution is,
