In the solution of the following set of linear equations by Gauss elimination using partial pivoting
5x + y + 2z = 34; 4y – 3z = 12; and
10x - 2y + z = – 4
the pivots for elimination of x and y are
  • a)
    10 and 4
  • b)
    10 and 2
  • c)
    5 and 4
  • d)
    5 and –4
Correct answer is option 'A'. Can you explain this answer?

In the solution of the following set of linear equations by Gauss elim...
5x + y + 2Z = 34
4y - 3z = 12
10x - 2y + z = -4
5, 0, 10
1st Pivoting
10x - 2y + z = -4.......eq1
4y - 3z = 12..............eq2
5x + y + 2z = 34.......eq3
eq3 - (eq1)/2,
10x - 2y + z = -4
4y - 3z = 12
2y + 3Z/2 = 36
4, 2
Hence, Pivot elements are x=10 & y=4
