1. **State the problem:** Solve the system of linear equations:
$$x + 2 + y = -2$$
$$3x - y = 5$$
2. **Rewrite the first equation:** Simplify the first equation by moving the constant term:
$$x + y = -2 - 2$$
$$x + y = -4$$
3. **Express one variable in terms of the other:** From the first equation,
$$y = -4 - x$$
4. **Substitute into the second equation:** Replace $y$ in the second equation:
$$3x - (-4 - x) = 5$$
5. **Simplify the equation:**
$$3x + 4 + x = 5$$
$$4x + 4 = 5$$
6. **Isolate $x$:**
$$4x = 5 - 4$$
$$4x = 1$$
7. **Divide both sides by 4:**
$$x = \cancel{\frac{4x}{4}} = \frac{1}{\cancel{4}}$$
8. **Find $y$ using $x$:** Substitute $x = \frac{1}{4}$ into $y = -4 - x$:
$$y = -4 - \frac{1}{4} = -\frac{16}{4} - \frac{1}{4} = -\frac{17}{4}$$
**Final answer:**
$$x = \frac{1}{4}, \quad y = -\frac{17}{4}$$
