IMO D

If (the number of used cars sold)x was(=) 10 (greater than) + (the number of new cars sold) y

I think the about format will help you.

The MGMAT Word Translation book is pretty good at explaining how to convert word problems into algebraic formulas, which this question essentially is.

Since the number of used cars sold was 10 greater than the number of new cars sold, we need to add 10 to the number of new cars sold to equal the number of used cars sold.

We can create the expression:

x = 10 + y

Answer: D
