To solve the absolute value equation
\[
13 - 4 |15 + 3x| + 3 = 16,
\]
we first simplify the left side:
\[
13 + 3 - 4 |15 + 3x| = 16,
\]
which simplifies to
\[
16 - 4 |15 + 3x| = 16.
\]
Next, we subtract 16 from both sides:
\[
-4 |15 + 3x| = 0.
\]
Dividing by -4, we find:
\[
|15 + 3x| = 0.
\]
The absolute value of an expression is zero only when the expression itself is zero. Thus, we set the inside of the absolute value to zero:
\[
15 + 3x = 0.
\]
Solving for \(x\), we subtract 15 from both sides:
\[
3x = -15,
\]
and then divide by 3:
\[
x = -5.
\]
Thus, the solution to the absolute value equation is
\[
\boxed{-5}.
\]
