So we're trying to find something that would end up having the same value as -1.5 - 2.75.
We can easily rule out A, because while we are subtracting negatives in the former equation, we are adding them both here. And then we can rule out B because in the middle, two negative signs make it a positive, and that would make -1.5 + 2.75, which is not what we're looking for. And then we can also rule out D, because 1.5 isn't a negative here, and in the original, it is a negative.
And that would make your answer C, because a negative and a positive make a negative, and that would make it -1.5 - 2.75, which is the exact same thing as the original equation. And they have the same values as well.
