Question 1085195
The sum of my tens and hundreds digit is my thousands digit. My hundreds digit is 1 less than my tens digit. My ones digit is greater than 7 and a multiple of 4. 
My tens digit is is 3 less than my ones digit. What is my number?
-------
Let the number be T*10^3 + h*10^2 + t*10 + u
--------
Equations:
T = t+h
h = t-1
u = 4k and u > 7 (So, u must be 8)
t = u-3
---------
Combining::
T = (u-3)+(u-3-1) = 2u-7 = 16-7 = 9
Also, T = t + t-1 = 2t-1
So 2t-1 = 9
Then t = 5
And h = t-1 = 4
