1. **State the problem:** Solve the system of equations:
$$x - 4y = 8$$
$$2x + y = -2$$
2. **Choose a method:** We will use substitution or elimination. Here, let's use substitution.
3. **Isolate one variable:** From the first equation, isolate $x$:
$$x = 8 + 4y$$
4. **Substitute into the second equation:** Replace $x$ in the second equation:
$$2(8 + 4y) + y = -2$$
5. **Simplify and solve for $y$:**
$$16 + 8y + y = -2$$
$$16 + 9y = -2$$
$$9y = -2 - 16$$
$$9y = -18$$
$$y = \frac{-18}{9}$$
$$y = -2$$
6. **Substitute $y$ back to find $x$:**
$$x = 8 + 4(-2)$$
$$x = 8 - 8$$
$$x = 0$$
7. **Final answer:**
$$\boxed{(x, y) = (0, -2)}$$
