1. **State the problem:** Solve the system of complex linear equations:
$$2z + w = 4 + i$$
$$6z - w = 8 + 2i$$
2. **Formula and rules:** We can solve this system by adding or subtracting equations to eliminate one variable, then solve for the other.
3. **Add the two equations to eliminate $w$:**
$$ (2z + w) + (6z - w) = (4 + i) + (8 + 2i) $$
$$ 2z + w + 6z - w = 12 + 3i $$
$$ 8z = 12 + 3i $$
4. **Solve for $z$:**
$$ z = \frac{12 + 3i}{8} = \frac{12}{8} + \frac{3i}{8} = 1.5 + 0.375i $$
5. **Substitute $z$ back into the first equation to find $w$:**
$$ 2z + w = 4 + i $$
$$ 2(1.5 + 0.375i) + w = 4 + i $$
$$ 3 + 0.75i + w = 4 + i $$
$$ w = (4 + i) - (3 + 0.75i) = 1 + 0.25i $$
6. **Final answer:**
$$ z = 1.5 + 0.375i, \quad w = 1 + 0.25i $$
