When +12x is added to -12x, this means that it will result to 0. Because of that, when equal number is added to each other but in an opposite signs, it will just result to 0. So, instead of us answering 0x, since it has no value, we just replace it with 0, because 0 = 0.
Additionally, we do not use such thing as 0x in Algebra. Even we don't see it in expressions.
