Question
Solve the given system of linear equations using the Elimination Method.
4.) 2x1 + 7x2 + 15x3 = -12
4x1 + 7x2 + 13x3 = -10
3x1 + 6x2 + 12x3 = -9
These is the example or guide that might help to solve the problem.
Transcribed Image Text:) Determine the values of x, y and w
3x - 2y + w : II
x + Sy - 2w : -9
2x + y - 3w = 6
Solution:
2(うメ- 2y+w)x-4y t2w- 22
X + Sy 2w = -9

7x +y
= 13
3(3x-2y tw = |1) + 9x -6y +3w =33
