1. **State the problem:** Solve the system of linear equations:
$$y = 0.5x + 4$$
$$-\frac{1}{3}x + y = -2$$
2. **Use substitution method:** Since $y$ is already expressed in terms of $x$ in the first equation, substitute $y = 0.5x + 4$ into the second equation.
3. **Substitute and simplify:**
$$-\frac{1}{3}x + (0.5x + 4) = -2$$
Combine like terms:
$$-\frac{1}{3}x + 0.5x + 4 = -2$$
Convert decimals to fractions for clarity: $0.5 = \frac{1}{2}$
$$-\frac{1}{3}x + \frac{1}{2}x + 4 = -2$$
4. **Find common denominator and combine $x$ terms:**
Common denominator is 6:
$$-\frac{2}{6}x + \frac{3}{6}x + 4 = -2$$
$$\left(-\frac{2}{6} + \frac{3}{6}\right)x + 4 = -2$$
$$\frac{1}{6}x + 4 = -2$$
5. **Isolate $x$:**
$$\frac{1}{6}x = -2 - 4$$
$$\frac{1}{6}x = -6$$
Multiply both sides by 6:
$$\cancel{6} \times \frac{1}{\cancel{6}} x = -6 \times 6$$
$$x = -36$$
6. **Find $y$ by substituting $x$ back into the first equation:**
$$y = 0.5(-36) + 4$$
$$y = -18 + 4$$
$$y = -14$$
7. **Final answer:**
$$\boxed{(x, y) = (-36, -14)}$$
