1. **State the problem:** Solve the system of linear equations:
$$13x - 6y = -2$$
$$8x + 3y = -22$$
2. **Choose a method:** We will use the elimination method to eliminate one variable.
3. **Make coefficients of $y$ opposites:** Multiply the first equation by 3 and the second equation by 6:
$$3(13x - 6y) = 3(-2) \Rightarrow 39x - 18y = -6$$
$$6(8x + 3y) = 6(-22) \Rightarrow 48x + 18y = -132$$
4. **Add the two equations to eliminate $y$:**
$$39x - 18y + 48x + 18y = -6 - 132$$
$$ (39x + 48x) + (-18y + 18y) = -138$$
$$87x + \cancel{-18y + 18y} = -138$$
$$87x = -138$$
5. **Solve for $x$:**
$$x = \frac{-138}{87} = \frac{\cancel{-138}^{-46} \times 3}{\cancel{87}^{29} \times 3} = -\frac{46}{29}$$
6. **Substitute $x$ back into one of the original equations to find $y$:** Use the second equation:
$$8x + 3y = -22$$
$$8\left(-\frac{46}{29}\right) + 3y = -22$$
$$-\frac{368}{29} + 3y = -22$$
7. **Isolate $y$:**
$$3y = -22 + \frac{368}{29}$$
Convert $-22$ to a fraction with denominator 29:
$$-22 = -\frac{638}{29}$$
$$3y = -\frac{638}{29} + \frac{368}{29} = -\frac{270}{29}$$
8. **Solve for $y$:**
$$y = \frac{-\frac{270}{29}}{3} = -\frac{270}{29} \times \frac{1}{3} = -\frac{270}{87} = -\frac{\cancel{270}^{90} \times 3}{\cancel{87}^{29} \times 3} = -\frac{90}{29}$$
**Final answer:**
$$x = -\frac{46}{29}, \quad y = -\frac{90}{29}$$
