To solve the inequality:

\[
-5 \leq \frac{5 - 3x}{2} \leq 8
\]

we can break it down into two separate inequalities:

1. \[
-5 \leq \frac{5 - 3x}{2}
\]
2. \[
\frac{5 - 3x}{2} \leq 8
\]

### Step 1: Solve the first inequality
\[
-5 \leq \frac{5 - 3x}{2}
\]

Multiply both sides by 2 to eliminate the denominator:
\[
-10 \leq 5 - 3x
\]

Now, subtract 5 from both sides:
\[
-15 \leq -3x
\]

Divide by -3, and remember to reverse the inequality sign because we are dividing by a negative number:
\[
5 \geq x
\]
or
\[
x \leq 5
\]

### Step 2: Solve the second inequality
\[
\frac{5 - 3x}{2} \leq 8
\]

Multiply both sides by 2:
\[
5 - 3x \leq 16
\]

Subtract 5 from both sides:
\[
-3x \leq 11
\]

Divide by -3, and reverse the inequality:
\[
x \geq -\frac{11}{3}
\]

### Final Solution
Now we combine the two inequalities:
\[
-\frac{11}{3} \leq x \leq 5
\]

This means the solution is:
\[
x \in \left[ -\frac{11}{3}, 5 \right]
\]
