The elementary row operation represented by \(-3R2 + 4R1\) involves multiplying the second row of the matrix by -3 and adding 4 times the first row to it. Let's perform this operation on matrix A:

Matrix A:

```

-3 5 2

8 -1 3

```

First, multiply the second row by -3:

```

-3 5 2

-24 3 -9

```

Next, add 4 times the first row to the second row:

```

-3 5 2

0 23 -34

```

So, the resulting matrix from the elementary row operation \(-3R2 + 4R1\) applied to matrix A is:

```

-3 5 2

0 23 -34

```
