Variable Separable 1
1. **Problem:** Solve the variable separable differential equation $y' = \frac{x^{-2}}{x^{-2}}$ passing through the point $(3, 2)$.
2. **Rewrite the equation:** Since both numerator and denominator are $x^{-2}$, simplify:
$$y' = \frac{x^{-2}}{x^{-2}} = 1$$
This means:
$$\frac{dy}{dx} = 1$$
3. **Separate variables:** The equation is already separated, so integrate both sides with respect to $x$:
$$\int dy = \int 1 \, dx$$
4. **Integrate:**
$$y = x + C$$
5. **Use initial condition $(3, 2)$ to find $C$:**
$$2 = 3 + C \implies C = 2 - 3 = -1$$
6. **Final solution:**
$$\boxed{y = x - 1}$$
This is the explicit solution passing through $(3, 2)$.
