Question

In the solution of the following set of linear
equations by Gauss elimination using partial
pivoting 5x + y + 2z = 34; 4y - 32 = 12; and
10x - 2y + z = - 4; the pivots for elimination of
x and y are
(a) 10 and 4
(c) 5 and 4
(b) 10 and 2
(d) 5 and - 4​

Answer 2

Answer:

I think answer is (b)

Step-by-step explanation:

4y-32=12    5x+11+2z=34      10x-22+z=-4

4y=44         5x+2z=23           10x+z=26

y=11

5x+2z=23

10x+z=26  /*2

5x+2z=23

20x+2z=52

-15x=-29

x=1.93
