![**Matrix Operations for Educational Purposes**
Start with the following matrix:
\[
\begin{bmatrix}
8 & -7 & 8 \\
-9 & -10 & 9 \\
-8 & -3 & -7 \\
\end{bmatrix}
\]
Perform the following 3 elementary row operations, one after the other, and give the resulting matrix at each step:
You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix.
### a) Add -2 times row 1 to row 2
**Operation Detail:**
- Multiply each element of row 1 by -2 and add the result to the corresponding element of row 2.
### b) Multiply row 3 by 5
**Operation Detail:**
- Multiply each element of row 3 by 5.
### c) Interchange rows 1 and 2
**Operation Detail:**
- Swap the elements of row 1 and row 2.
