Let x be the cost of one textbook.
The cost of the other textbook is then x + 9.
The sum of the two textbooks is x + (x + 9) = $65 in total.
This equation can be simplified as 2x + 9 = $65.
The cost of the other textbook is then x + 9.
The sum of the two textbooks is x + (x + 9) = $65 in total.
This equation can be simplified as 2x + 9 = $65.
