Obtain an equivalent system by performing the stated elementary operation on the system.Interchange equations 1 and 3.5x + 2y + z = -183x - 2y - z = 23x + 4z = -3
A. 3x + 4z = -3 3x - 2y - z = 2 5x + 2y + z = -18 B. 3x - 2y - z = 2 5x + 2y + z = -18 3x + 4z = -3 C. x + 2y + 5z = -18 3x - 2y - z = 2 3x + 4z = -3 D. 3x + 4z = -3 5x + 2y + z = -18 3x - 2y - z = 2
