The sum of the two digits of a number is 16. the number formed by reversing the digits is 18 more than the original number. determine the original number.

let t = the tens digit, u = the units digit, and u + t = 16. which of the following equations would complete the system?

9t - 9u = 18
9u - 9t = 18
tu = ut + 18
