Obtain an equivalent system by performing the stated elementary operation on the system. Replace the third equation by the sum of itself and -1 times the second equation. x - 2y - 7z = 17-9x + 4y + 8z = -9 7x + 6y - z = -4
A. x - 2y - 7z = 17 -9x + 4y + 8z = -9 -16x - 2y + 9z = 5 B. x - 2y - 7z = 17 16x + 2y - 9z = 5 7x + 6y - z = -4 C. x - 2y - 7z = 17 -9x + 4y + 8z = -9 -2x + 10y + 7z = -13 D. x - 2y - 7z = 17 -9x + 4y + 8z = -9 16x + 2y - 9z = 5
