Obtain an equivalent system by performing the stated elementary operation on the system.Interchange equations 1 and 3.4x + 4y + z = -12x - 5y - z = 163x + 5z = 18
A. 3x + 5z = 18 2x - 5y - z = 16 4x + 4y + z = -1 B. 2x - 5y - z = 16 4x + 4y + z = -1 3x + 5z = 18 C. 3x + 5z = 18 4x + 4y + z = -1 2x - 5y - z = 16 D. x + 4y + 4z = -1 2x - 5y - z = 16 3x + 5z = 18
