4. Solve the system of linear equations by using the Gauss-Jordan (Matrix) Elimination Method. No credit in use any other method. Use exactly the notation we used in class and in the text. Indicate whether the system has a unique solution, no solution, or infinitely many solutions. In the latter case, present the solutions in parametric form. 3x + 6y + 3z = -6 -2x -3y -z = 1 x +2y + z = -2

The system of equations may have a unique solution, an infinite number of solutions, or no solution. Use matrices to find the general solution of the system, if a solution exists. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, express your answers in terms of z as in Example 3.) 3x ? 2y + 5z = 11 2x ? 3y + 4z = 8

his is a linear algebra problem Determine the values of a for which the system has no solutions, exactly one solution, or infinitely many solutions. x + 2y - 2z = 3 3x - y + 2z = 3 5x + 3y + (a^2 - 11)z = a + 6 For a = there is no solution. For a = there are infinitely many solutions. For a ≠ ± the system has exactly one solution.
