2. The Gauss-Jordan method can be used to solve a linear system when it has exactly one solution. Suppose a linear system is given in the matrix form Ax = b. This can be done as follows: • Set up the augmented matrix {A : b} Apply the appropriate elementary matrix operations to transform A into the identity matrix I. • If done correctly, then the augmented matrix will have the form {I : s}, from which the solution can be easily read off. Use this technique to solve the following linear system: x + y +z+ w = 13 2x + 3y w=-1 -3x + 4y +z+2w = 10 x + 2yz + w= 1
