one number is twice another number. the sum of their reciprocals is one half. find the numbers
----
Equations:
x = 2y
1/x + 1/y = 1/2
----------------
Substitute for "x" and solve for "y":
1/2y + 1/y = 1/2
----
Multiply thru by 2y to get:
1 + 2 = y
y = 3
------
Solve for "x":
x = 2y
x = 6
---------
