1. **State the problem:** Solve the system of linear equations:
$$6x - 5y = 8$$
$$-12x + 2y = 0$$
2. **Identify the method:** We will use the elimination method to solve for $x$ and $y$.
3. **Eliminate one variable:** Multiply the second equation by $\frac{5}{2}$ to align the coefficients of $y$:
$$\frac{5}{2} \times (-12x + 2y) = \frac{5}{2} \times 0$$
$$-30x + 5y = 0$$
4. **Add the two equations:**
$$6x - 5y = 8$$
$$-30x + 5y = 0$$
Adding:
$$6x - 5y + (-30x + 5y) = 8 + 0$$
$$6x - 30x + (-5y + 5y) = 8$$
$$-24x + \cancel{-5y + 5y} = 8$$
Simplifies to:
$$-24x = 8$$
5. **Solve for $x$:**
$$x = \frac{8}{-24} = \cancel{\frac{8}{-24}} = -\frac{1}{3}$$
6. **Substitute $x$ back into one equation:** Use the second original equation:
$$-12x + 2y = 0$$
Substitute $x = -\frac{1}{3}$:
$$-12 \times \left(-\frac{1}{3}\right) + 2y = 0$$
$$4 + 2y = 0$$
7. **Solve for $y$:**
$$2y = -4$$
$$y = \frac{-4}{2} = -2$$
**Final answer:**
$$x = -\frac{1}{3}, \quad y = -2$$
