x + 2y - z = 1
-2x - y + z = -4
-2x - y + z = -4
a) The system does not have a solution.
b) [x = 4s - 2, y = -4, z = -10 + 5s]
c) [x = 3s - 3, y = 2s, z = -10]
d) [x = s, y = -3 + s, z = -7 + 3s]
e) [x = 3, y = -2s, z = -9]
f) None of the above.
Question 6
Give the solution set to the system of equations
2x + 3y + 2z = -1
-2x - 4y - 2z = 1
x + 2y + z = -1
a) [x = 3s - 1, y = 2 - 2s, z = -2s + 1]
b) [x = 3 + 3s, y = -2s, z = 2 - s]
c) [x = 3s - 1, y = 2s + 3, z = -1 - s]
d) [x = 4s + 1, y = -2s, z = 1 - s]
e) The system does not have a solution.
