You can put this solution on YOUR website! The sum of the two digit number is 8, and their difference is 6. If the value of the number is less than 50, what is the number?
--------------------
Let the two-digit number be 10t+u where t is the tens and u is the units digit.
-----------------------
EQUATION:
u + t = 8
u - t = 6
------------
Add to solve for "u":
2u = 14
u =7
Substitute in u+t=8 to get t=1
----------------
The number is 10*1+7 = 17
