Obtain an equivalent system by performing the stated elementary operation on the system.Multiply the third equation by 1/4.3x - y + 4z + w = -104x - z - 2w = 34x - 8y + 3z - w = -20 x + 3y - 8z = 1
A. 3x - y + 4z + w = -10
4x - z - 2w = 3
x - 2y + 
z + 
w = -20
x + 3y - 8z = 1
B. 3x - y + 4z + w = -10
4x - z - 2w = 3
x - 2y + 
z - 
w = -5
x + 3y - 8z = 1
C. 3x - y + 4z + w = -10
4x - z - 2w = 3
x - 8y + 3z - w = -20
x + 3y - 8z = 1
D. 3x - y + 4z + w = -10
4x - z - 2w = 3
x - 2y + 
z - 
w = -20
x + 3y - 8z = 1
