To solve the system of equations using substitution, we have:
1. \(-10x + 3y = 16\)
2. \(y = -8\)
Since the second equation already gives us the value of \(y\), we can substitute \(y = -8\) into the first equation.
Substituting \(y\) into the first equation:
\[
-10x + 3(-8) = 16
\]
Calculating \(3(-8)\):
\[
-10x - 24 = 16
\]
Next, we isolate the term with \(x\):
\[
-10x = 16 + 24
\]
\[
-10x = 40
\]
Now, divide by -10:
\[
x = \frac{40}{-10} = -4
\]
Now we have both \(x\) and \(y\):
\[
x = -4, \quad y = -8
\]
Thus, the solution to the system of equations is:
\[
\boxed{(-4, -8)}
\]
