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 + 8y + 6z = -9 5x + 3y - z = -4
A. x - 2y - 7z = 17 -9x + 8y + 6z = -9 -14x + 5y + 7z = 5 B. x - 2y - 7z = 17 -9x + 8y + 6z = -9 14x - 5y - 7z = 5 C. x - 2y - 7z = 17 14x - 5y - 7z = 5 5x + 3y - z = -4 D. x - 2y - 7z = 17 -9x + 8y + 6z = -9 -4x + 11y + 5z = -13
