Question: Repeat Exercise 2 using Algorithm 6.2. In Exercise 2 a. 13x1 + 17x2 + x3 = 5, x2 + 19x3 = 1, 12x2 x3

Repeat Exercise 2 using Algorithm 6.2.
In Exercise 2
a. 13x1 + 17x2 + x3 = 5,
x2 + 19x3 = 1,
12x2 − x3 = 0
b. x1 + x2 − x3 = 0,
12x2 − x3 = 4,
2x1 + x2 + x3 = 5
c. 5x1 + x2 − 6x3 = 7,
2x1 + x2 − x3 = 8,
6x1 + 12x2 + x3 = 9
d. x1 − x2 + x3 = 5,
7x1 + 5x2 − x3 = 8,
2x1 + x2 + x3 = 7
