An integer is 12 unit from 4 and 4 units from -4. What is the integer? Explain.

-8

So, an integer is 12 units away from 4. This could either be positive or negative. If it was positive, it would be 16. If it was negative, it would be -8. Though at this point we don’t know. Then the question goes on saying that it’s 4 units away from -4. This could be positive, 0, or negative, -8. Before, we got a similar answer of -8. So, I conclude that the answer is -8.
