**Find the inverse of the matrix, if it exists.**

Matrix \( A \) is given by:

\[ A = \begin{bmatrix} -5 & -5 \\ 2 & 2 \end{bmatrix} \]

Choose the correct option for the inverse of matrix \( A \):

1. \(\begin{bmatrix} \frac{2}{21} & \frac{5}{21} \\ -\frac{2}{21} & -\frac{5}{21} \end{bmatrix}\)

2. \(\begin{bmatrix} \frac{2}{21} & -\frac{5}{21} \\ -\frac{2}{21} & \frac{5}{21} \end{bmatrix}\)

3. \(\begin{bmatrix} -\frac{2}{21} & -\frac{5}{21} \\ \frac{2}{21} & \frac{5}{21} \end{bmatrix}\)

4. \( A \) is not invertible
