Multiple Choice
Write the system of linear equations as represented by the augmented matrix. Utilize the variables x, y, and z.
A) -4x + 7y - 2z = 15
10x - 18y + 19z = -30
20x + 12y + 17z = 9
B) -4x - 7y + 2z = 15
10x + 18y + 19z = -30
20x + 12y + 17z = 9
C) -4x + 7y - 2z = -15
10x - 18y + 19z = -30
20x - 12y - 17z = 9
D) -4x + 7y - 2z = -30
10x - 18y + 19z = 15
20x - 12y + 17z = 9
