The sum of the reciprocals of two numbers is 7. the larger reciprocal exceeds the smaller one by 7/3. find the numbers. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The sum of the reciprocals of two numbers is 7. the larger reciprocal exceeds the smaller one by 7/3. find the numbers.
------------------------
Equations:
1/x + 1/y = 7
1/x = 1/y + 7/3
-----------------------
1/x = 7-(1/y)
Substitute:
7-(1/y) = (1/y)+(7/3)
(2/y) = 7-(7/3)
2/y = 14/3
y/2 = 3/14
y = 6/14
y = 3/7
----------------
So 1/y = 7/3
---
Substitute to solve for "x":
1/x + (7/3) = 7
1/x = 14/3
x = 3/14
