The sum of the digits of a two digit number is 14. The first digit is 4 less than the second digit. What is the original number?
--------------------------
Let the number be 10t+u
-----
Equations:
t + u = 14
t = u-4
----
Substitute for "t" and solve for "U":
u-4+u = 14
2u = 18
u = 9
---
Solve for "t":
t = 9-4 = 5
----
Ans: 59
