Answer:
The answer is x + 12, where x is less than -12.
Explanation:
If x is less than -12, then x-(-12) would be greater than -12-(-12), which simplifies to -12+12, which equals 0.
So, x-(-12) would be greater than 0, but we don't know the exact value of x, so we cannot simplify further. The expression would be x-(-12) or x+12, where x is less than -12.
