<PRE><B>Question 546187</B>
The 4 digits, a, b, c, d
:
write an equation for each statement:
:
my tens digit is 3 more than my thousands digit
c = a+3
:
my ones digit is 2 times my hundreds digit
d = 2b
:
my tens digit is 4 times my hundreds digit
c = 4b
:
 my tens digit is 1 more than 7
c = 8
:
From the above equations we can say:
If c = 8, then b = 2, if b = 2 then d = 4, if c = 8 then a = 5
therefore, 
5284 is the number</PRE>
