Write the equations: Two of Julie’s textbooks are a total of $65. The difference in price between the two books is $9. What is the cost of each book

so what will the equation be for the difference in price between the two books?

Let's say the cost of one book is "x" dollars.

According to the problem, the total cost of the two books is $65. So, the equation for the total cost is x + (x + 9) = 65.
