1. **State the problem:** Solve the system of linear equations using the elimination method:
$$5x + 4y = -14$$
$$x + 6y = 6$$
2. **Explain the elimination method:** The goal is to eliminate one variable by adding or subtracting the equations after multiplying them by suitable numbers.
3. **Multiply the second equation by -5 to align coefficients of $x$:**
$$-5(x + 6y) = -5(6)$$
$$-5x - 30y = -30$$
4. **Add this to the first equation:**
$$5x + 4y = -14$$
$$-5x - 30y = -30$$
Adding gives:
$$0x - 26y = -44$$
5. **Simplify the resulting equation:**
$$-26y = -44$$
6. **Solve for $y$:**
$$y = \frac{-44}{-26} = \frac{22}{13}$$
7. **Substitute $y = \frac{22}{13}$ into the second original equation to find $x$:**
$$x + 6\left(\frac{22}{13}\right) = 6$$
$$x + \frac{132}{13} = 6$$
$$x = 6 - \frac{132}{13} = \frac{78}{13} - \frac{132}{13} = -\frac{54}{13}$$
8. **Final solution:**
$$x = -\frac{54}{13}, \quad y = \frac{22}{13}$$
