Please help. This is my problem.

Today the center City baseball team scored 10 runs . The day before yesterday they scored x. How many runs did they score in these two days.

If i told you that yesterday you had 3 apples, and today you had 2, could you figure out how many you had during both days?

Sure you could. Just add them up: 10+x
Never mind what x is. Just know that whatever it is, adding 10 to it will give you the total runs.
