1. **State the problem:** Solve the system of linear equations:
$$-2x = y$$
$$4x + 10y = 16$$
2. **Use substitution method:** From the first equation, express $y$ in terms of $x$:
$$y = -2x$$
3. **Substitute $y$ into the second equation:**
$$4x + 10(-2x) = 16$$
4. **Simplify the equation:**
$$4x - 20x = 16$$
$$\cancel{4x} - 20x = 16$$
$$-16x = 16$$
5. **Solve for $x$:**
$$x = \frac{16}{-16} = -1$$
6. **Find $y$ using $y = -2x$:**
$$y = -2(-1) = 2$$
7. **Final answer:**
$$x = -1, \quad y = 2$$
This means the solution to the system is the point $(-1, 2)$ where both lines intersect.
