Consider the system of equations x1 - 2x2 + 2x3 = 1, -3x1 - x2 + x3 = 4, x1 + 5x2 - 12x3 = 8. (a) Use the Gaussian elimination method to reduce the system to upper triangular form. Clearly label the operations that you use. (b) If the system has no solution, then clearly state this; if it has a unique solution, then find it; and if it has an infinite number of solutions, then find the most general solution.
