Answer:
A ; y = 2229-x
Step-by-step explanation:
The question is asking for us to find how many seats are left that can be sold. There are 2463 total seats, 234 reserved seats, and x non-reserved seats.
If we subtract the 234 reserved seats from total seats, we will get 2229, the number of non-reserved seats and the not sold seats.
Since x is the non-reserved seats, we can subtract x from 2229 to get the number of seats that aren't sold.
