Use Gauss-Jordan elimination to nd the general solution for the following system of linear equations: z2 + 3z3 ???? z4 = 0 ????z1 ???? z2 ???? z3 + z4 = 0 ????2z1 ???? 4z2 + 4z3 ???? 2z4 = 0 (b) Give an example of a non-zero solution to the previous system of linear equations. (c) The points (1; 0; 3), (1; 1; 1), and (????2;????1; 2) lie on a unique plane a1x1 + a2x2 + a3x3 = b. Using your previous answers, nd an equation for this plane. (Hint: think about the relationship between the previous system and the one you would need to solve in this question.)

Final answer:

To find the general solution for the system of linear equations using Gauss-Jordan elimination, we first write the augmented matrix and perform row operations to obtain row-echelon form. An example of a non-zero solution is provided. The equation of the plane passing through given points is also found.

Step-by-step explanation:

To solve the given system of linear equations using Gauss-Jordan elimination, we first write the augmented matrix:

. 1 -1 -1 1 0

. 0 1 3 -2 0

. 2 4 4 -2 0

Perform row operations to transform the augmented matrix into row-echelon form:

. 1 -1 -1 1 0

. 0 1 3 -2 0

. 0 0 0 0 0

From the row-echelon form, we can form the system of equations as:

. z1 - z2 - z3 + z4 = 0

. z2 + 3z3 - 2z4 = 0

Since we have a free variable (z4), we can express the solutions in terms of it.

An example of a non-zero solution is: z1 = 1, z2 = -1, z3 = 0, z4 = 1.

The points (1, 0, 3), (1, 1, 1), and (-2, -1, 2) lie on the plane defined by the equation 2x - y + z = 3.
