Question 762740: The sum of the reciprocals of 2 consecutive odd integers is 16/63. Find the numbers.
I was thinking that the equation was 1/x + 1/x+2= 16/63
Not sure if this is correct.
Please help.

Consecutive ODD numbers, 2x%2B1 and 2x%2B3.
Without the factor 2, each of the numbers may be either odd or even.

NOW, 1%2F%282x%2B1%29%2B1%2F%282x%2B3%29=16%2F63 and you can solve according to number properties which you have been studying. Start by multiplying lefthand and righthand members by the LCD, which is 63%282x%2B1%29%282x%2B3%29.

----
1st odd number: x-1
2nd odd number: x+1
-----
1/(x-1) + 1/(x+1) = 16/63
------
Multiply thru by 63(x-1)(x+1) to get:
63(x+1) + 63(x-1) = 16(x^2-1)
------------------------------------
126x = 16x^2 - 16
16x^2 - 126x - 16 = 0
----
8x^2 - 63x - 8 = 0
(x-8)(8x+1) = 0
----
Whole number solution:
x = 8
====
1st odd number: 2x-1 = 15
2nd odd number: 2x+1 = 17
