There are 3 + x apples. Since x=12, there are 3 + 12 apples or 15 apples.

The variable x is used to describe an unknown number. You know that George has 3 apples and Bettey has a (unknown) number of apples.
You can write this 3 + x = t
t is another variable that is not x (it can be whatever you want) to indicate the total number of apples, because George's apples (3) plus Bettey's apples (x) = total apples (t).
In this case, the problem is easy because the book gives you the value of x. Simply plug in the value of x to solve for t.
x = 12
3 + 12 = t
t = 15 apples
So the total (t) combined = 15 apples
