<PRE><B>Question 1032428</B>
Two numbers differ by 3 . The sum of their reciprocal is 7/10 find the numbers 
-----------
x - y = 3
(1/x) + (1/y) = 7/10
---------------------------
x - y = 3
10y + 10x = 7
---------------------
x - y = 3
x + y = 0.7
-----
2x = 3.7
x = 1.85
-----
y = 0.7-1.85 = -1.15
--------------------------
