pick x and you get 9 * x + 9 which is divisible by 9. As a rule, any number divisible by 9 has the sum of its digits divisible by 9, and in this case, because x is in the [1, 9] interval you always get 9.
I'm glad you all enjoyed my performance in #9. In 20012, I'm planning on releasing a sequel once I'm finished with this silly lawsuit brought against me by the ASPCA.
