Kiddo bro ko problem ko no solution re, http://onlinemschool.com/math/assistance/equation/gaus/ le bhanya,
Solution:
Rewrite the system in matrix form and solve it by Gaussian Elimination (Gauss-Jordan elimination)
7 5 3 26
2 1 3 5
8 6 2 44
devide the 1-th row by 7
1 5/7 3/7 26/7
2 1 3 5
8 6 2 44
from 2; 3 rows we subtract the 1-th row, multiplied respectively by 2; 8
1 5/7 3/7 26/7
0 -3/7 15/7 -17/7
0 2/7 -10/7 100/7
devide the 2-th row by -3/7
1 5/7 3/7 26/7
0 1 -5 17/3
0 2/7 -10/7 100/7
from 1; 3 rows we subtract the 2-th row, multiplied respectively by 5/7; 2/7
1 0 4 -1/3
0 1 -5 17/3
0 0 0 38/3
Answer:
The system of equations has no solution because: 0 ≠ 38/3
