We need to translate the word problem to an algebraic expression:

First, we have 63 decreased, where the word decreased in this kind of problem refers to subtraction.

Now, twice a number refers to the multiplication of a number by 2.

We need to use n for the unknown number, Then, we can write it as 2n.

Hence, the whole expression can be written as 63 -2n.
