1. **State the problem:** Solve the system of linear equations:
$$2x + 2y = 8$$
$$2x - y = 2$$
2. **Choose a method:** We will use the substitution or elimination method. Here, elimination is straightforward.
3. **Eliminate one variable:**
Multiply the second equation by 2 to align the coefficients of $y$:
$$2(2x - y) = 2(2) \Rightarrow 4x - 2y = 4$$
4. **Add the first equation and the new equation:**
$$2x + 2y = 8$$
$$4x - 2y = 4$$
Adding:
$$2x + 2y + 4x - 2y = 8 + 4$$
Simplify:
$$6x + \cancel{2y} - \cancel{2y} = 12$$
$$6x = 12$$
5. **Solve for $x$:**
$$x = \frac{12}{6}$$
$$x = 2$$
6. **Substitute $x=2$ into one original equation to find $y$:**
Using the second equation:
$$2(2) - y = 2$$
$$4 - y = 2$$
7. **Solve for $y$:**
$$-y = 2 - 4$$
$$-y = -2$$
$$y = 2$$
**Final answer:**
$$x = 2, \quad y = 2$$
