Problem1:Find the augmented matrix for the following system of linear equations |
> ;
v + 2 w - y + z = 1
3 w + x - z = 2
x + 7 y = 1
|
|
SOLUTION:
| Since there are 3 equations and 5 unknowns (v,w,x,y,z) the augmented matrix must be 3 rows and (5+1) columns. In maple, |
> matrix(3,6,[1,2,0,-1,1,1, 0,3,1,0,-1,2, 0,0,1,7,0,1]);
[1 2 0 -1 1 1]
[ ]
[0 3 1 0 -1 2]
[ ]
[0 0 1 7 0 1]
