The problem in the image provides the following system of equations involving real numbers \(a\), \(b\), and \(c\):

\[
a^2 + 27 = -8b + 10c
\]
\[
b^2 + 196 = 18c + 13a
\]
\[
c^2 + 119 = -3a + 30b
\]

We are asked to find the value of \(a + 3b + 5c\).

### Steps to Solve:
1. First, we will simplify and rearrange each equation to get expressions for \(a^2\), \(b^2\), and \(c^2\) in terms of \(a\), \(b\), and \(c\).
2. Then, using substitution or elimination, we will attempt to solve the system step by step.
3. Finally, we will substitute the values of \(a\), \(b\), and \(c\) into the expression \(a + 3b + 5c\) to find the required value.

Let me begin solving it systematically.

The system of equations yields the solution \(a = 5\), \(b = 11\), and \(c = 14\).

Substituting these values into the expression \(a + 3b + 5c\), we get:

\[
a + 3b + 5c = 5 + 3(11) + 5(14) = 5 + 33 + 70 = 108
\]

Thus, the value of \(a + 3b + 5c\) is \(108\).
