What is 18-(4x-12)? i really need the for my homework

The answer would be 2(15-2x)

I hope this helped you.

We don't not know what would x really equal. So when solving this, it would look like the problem would be not quite finished, but it would be, so we would be subtracting this, but keeping x as it's self.

Let's talk x out of the whole problem.

(4-12) = 8. This would be the answer so far.

Then we do, (8-18) = 10.

Now we can bring x back in the problem.

Your answer would be (10x).
