The sum of the digits of a two digit number is 8. The value of the number is 2 less than 11 times the tens digit.Find the number.
----
Let the original number be 10t+u
---
Equations:
t + u = 8
10t+u = 11t-2
------------------------
Simplify the 2nd equation:
t=u+2
----
Substitute into the 1st equation and for for "u":
u+2 + u = 8
2u = 6
u = 3
----
Since t=u+2, t = 5
----
Original Number: 53
