### Differential Equations Problem

Consider a first-order differential equation given by:

\[ \frac{dy}{dx} = \frac{1+x}{xy} \]

with the condition \( x > 0 \), and the initial value \( y = -4 \) when \( x = 1 \). Determine the value of \( y \) when \( x = 3 \).

The options provided for \( y \) when \( x = 3 \) are:

1. \( \circ \, 4.711 \text{ and } -4.711 \)
2. \( \circ \, 3.898 \text{ and } -3.898 \)
3. \( \circ \, -4.711 \text{ only} \)
4. \( \circ \, 3.898 \text{ only} \)

#### Explanation:
To solve this, you need to either integrate the differential equation or use a numerical solver to find the value of \( y \) at \( x = 3 \) given the initial condition.

For detailed step-by-step instructions on solving such differential equations, please refer to the section on "Solving First-Order Differential Equations" in the calculus module.
