In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
[tex]\begin{bmatrix}{1} & {5} & {2} \\ {1} & {1} & {7} \\ {0} & {-3} & {4}\end{bmatrix}[/tex]
Step 02:
inverse matrix:
= 1 5 2 | 1 0 0
1 1 7 | 0 1 0
0 -3 4 | 0 0 1
= 1 0 0 | - 25 26 - 33
0 1 0 | 4 -4 5
0 0 1 | 3 -3 4
The answer is:
- 25 26 - 33
4 -4 5
3 -3 4
