Question
The task on this page involves finding the inverse of a given matrix using row reduction. The instructions are as follows:

"Use row reduction to find the inverse of the given matrix if it exists, and check your answer by multiplication. (If the inverse doesn't exist, enter DNE in any cell of the matrix.)"

The matrix provided is:
```
[ 1  4  2 ]
[ 0  1  2 ]
[ 0  0  1 ]
```

Below the matrix, there is an indicator showing a need to solve the problem with a red "X," suggesting that an incorrect or incomplete solution has been attempted. 

There is a small prompt at the bottom that reads, "Need Help?" with options to "Read It" and "Watch It," possibly linking to additional resources or tutorials for further assistance.
