Answer:
The system has infinite solutions described in the set
Step-by-step explanation:
The augmented matrix of the system is .
We apply row operations:
1. We add the first row to the second row twice and obtain the matrix
2. multiply by -1 the rows of the previous matrix and obtain the matrix that is the reduced echelon form of the matrix associated to the system.
Now we aply backward substitution:
1. Observe that the reduced echelon form has a free variable, then the system has infinite solutions.
2.
3.
.
Then the set of solutions is
