To solve the system of linear equations:

[tex]\[ \left\{ \begin{array}{l} -3a + 7b = -16 \\ -9a + 5b = 16 \end{array} \right. \][/tex]

we need to find the values of [tex]\(a\)[/tex] and [tex]\(b\)[/tex].

Based on the provided solution steps and the obtained numerical results, we determine the solution as follows:

The solution to this system of equations yields:

[tex]\[ a = -4 \][/tex]
[tex]\[ b = -4 \][/tex]

Therefore, the correct statement about the solution to this system of equations is:

The values of [tex]\(a\)[/tex] and [tex]\(b\)[/tex] are both equal to [tex]\(-4\)[/tex].
