Question 1142439
The number is
N x x x M
M > N
M is either 4, 5, or 6
N + M + 3x = 19
x cannot be 9
x cannot be 8
x cannot be 7
x cannot be 6
------------------------
Suppose x is 5
N + M + 3*5 = 19
N + M = 4
M must be 4 and N must be 0
The number is
05554 -cannot be
--------------------------------
Suppose x is 4
N + M + 3*4 = 19
N + M = 7
If M is 6, then N is 1
number is:
14446 -out of range
If M is 4, the N is 3 -also out of range
-----------------------------------------
Suppose x is 3
N + M + 3*3 = 19
N + M = 10
If M is 6, then N is 4
number is:
43336 
the number is in range
-----------------------------
If x is 2, then
 M + N + 6 = 19
M + N = 13
52228 works
62227 works
---------------------
If x is 1
M + N + 3*1 = 19 
M + N = 16
this makes number out of range
( N is 10 or greater )
---------------------------------------
The possible numbers are:
43336
52228
62227
