You can put this solution on YOUR website! Problem 1. The sum of the digits of a two-digit number is 14. If the digits are reversed, the number is increased by 18. What is the number?
------
Let the number be 10t+u
The reversed number is 10u+t
Equations:
t + u = 14
10u+t - (10t+u) = 18
---------------------------
Simplify the 2nd equation
t + u = 14
u - t = 2
---
Add to get 2u = 16
u = 8
Then t = 6
---
1st number: 68
