1. **State the problem:** Solve the system of linear equations:
$$-8x + 4y = -24$$
$$-7x + 4y = -16$$
2. **Method:** We will use the elimination method to solve for $x$ and $y$.
3. **Step 1: Subtract the second equation from the first to eliminate $y$:**
$$(-8x + 4y) - (-7x + 4y) = -24 - (-16)$$
Simplify:
$$-8x + 4y + 7x - 4y = -24 + 16$$
$$(-8x + 7x) + (4y - 4y) = -8$$
$$-x + 0 = -8$$
So,
$$-x = -8$$
4. **Step 2: Solve for $x$:**
$$x = 8$$
5. **Step 3: Substitute $x=8$ into one of the original equations to find $y$. Use the first equation:**
$$-8(8) + 4y = -24$$
Simplify:
$$-64 + 4y = -24$$
6. **Step 4: Solve for $y$:**
Add 64 to both sides:
$$4y = -24 + 64$$
$$4y = 40$$
Divide both sides by 4:
$$\cancel{4}y = \cancel{4}10$$
$$y = 10$$
7. **Final answer:**
$$x = 8, \quad y = 10$$
