Solve each of the systems in Exercise 6 by Gaussian elimination. In Exercise 6 (a) x1 +

Question:

Solve each of the systems in Exercise 6 by Gaussian elimination.
In Exercise 6
(a) x1 + x2 + 2x3 = 8
- x1 - 2x2 + 3x3 = 1
3x1 - 7x2 + 4x3 = 10
(b) x - y + 2z - w = - 1
2x + y - 2z - 2w = - 2
- x + 2y - 4z + w = 1
3x - 3w = - 3
