The total that Rajan spent on 5 books was $2 more than he would have spent on 4 copies of the book at the original price
5x - 2 = 4y
x = y - 5
Substitute:
5(y - 5) -2 = 4y
5y - 25 - 2 = 4y
y = 27
x = 22

y = 27
x = 22
x = 22
So, x is the sale book and y is the non-sale book, because 22 is the lesser amount.
