You can put this solution on YOUR website! Four digits: w,x,y,z
I am a 4 digit number. two of my digits are odd numbers less than 9.
Two digits; 7, 5, 3 or 1
:
My tens digit is even and is 3 less than my greatest odd digit.
y = 7 - 3, or y = 5 - 3
:
My hundreds digit is the sum of my thousands digit and my ones digit.
x = w+z
:
my tens digit is twice my ones digit.
y = 2z;
we know y = 4 or 2
then
z = 2 or 1
:
try y = 4, z = 2, w and x are odd, x = 7 greatest odd; 7 = w + 2; w=5
;
we have: 5 7 4 2 seems to conform to these conditions
