1. **State the problem:** Solve the system of linear equations:
$$-x + y = 4$$
$$y = 2x + 2$$
Find the values of $x$ and $y$ where these two lines intersect.
2. **Use substitution method:** Since the second equation is already solved for $y$, substitute $y = 2x + 2$ into the first equation.
$$-x + (2x + 2) = 4$$
3. **Simplify the equation:**
$$-x + 2x + 2 = 4$$
$$x + 2 = 4$$
4. **Solve for $x$:**
$$x + 2 = 4$$
$$x = 4 - 2$$
$$x = 2$$
5. **Find $y$ by substituting $x=2$ into $y = 2x + 2$:**
$$y = 2(2) + 2$$
$$y = 4 + 2$$
$$y = 6$$
6. **Final answer:** The lines intersect at the point $(2, 6)$.
