You have a system of two linear equations:

\[
3x + 5y = -4 \tag{1}
\]
\[
x - 2y = -1 \tag{2}
\]

### Step 1: Solve Equation (2) for \( x \)
From equation (2):

\[
x = 2y - 1
\]

### Step 2: Substitute \( x \) into Equation (1)
Substitute \( x = 2y - 1 \) into equation (1):

\[
3(2y - 1) + 5y = -4
\]

Expand the equation:

\[
6y - 3 + 5y = -4
\]

Simplify:

\[
11y - 3 = -4
\]

### Step 3: Solve for \( y \)
Add 3 to both sides:

\[
11y = -1
\]

Now, divide by 11:

\[
y = -\frac{1}{11}
\]

### Step 4: Solve for \( x \)
Now, substitute \( y = -\frac{1}{11} \) back into the expression for \( x \):

\[
x = 2\left(-\frac{1}{11}\right) - 1
\]

Simplify:

\[
x = -\frac{2}{11} - 1 = -\frac{2}{11} - \frac{11}{11} = -\frac{13}{11}
\]

### Final Answer:
The solution to the system is:

\[
x = -\frac{13}{11}, \quad y = -\frac{1}{11}
\]
