1. **Problem:** Find four consecutive even integers such that 4 times the sum of the first and fourth is 8 greater than 12 times the third.
2. **Step 1: Define variables.** Let the first even integer be $x$. Then the next three consecutive even integers are $x+2$, $x+4$, and $x+6$.
3. **Step 2: Write the equation from the problem statement.**
$$4 \times (x + (x+6)) = 12 \times (x+4) + 8$$
4. **Step 3: Simplify inside parentheses.**
$$4 \times (2x + 6) = 12(x+4) + 8$$
5. **Step 4: Distribute multiplication.**
$$8x + 24 = 12x + 48 + 8$$
6. **Step 5: Simplify right side.**
$$8x + 24 = 12x + 56$$
7. **Step 6: Rearrange to isolate $x$.**
$$8x + 24 - 12x = 56$$
$$\cancel{8x} + 24 - \cancel{12x} = 56 - 4x$$
Actually, subtract $12x$ from both sides:
$$8x - 12x + 24 = 56$$
$$-4x + 24 = 56$$
8. **Step 7: Subtract 24 from both sides.**
$$-4x = 56 - 24$$
$$-4x = 32$$
9. **Step 8: Divide both sides by -4.**
$$x = \frac{32}{-4} = -8$$
10. **Step 9: Find the four integers.**
$$x = -8, \quad x+2 = -6, \quad x+4 = -4, \quad x+6 = -2$$
11. **Answer:** The four consecutive even integers are $-8$, $-6$, $-4$, and $-2$.
**Verification:**
Calculate left side:
$$4 \times (-8 + (-2)) = 4 \times (-10) = -40$$
Calculate right side:
$$12 \times (-4) + 8 = -48 + 8 = -40$$
Both sides equal, so solution is correct.
