Rewrite this so it makes sense.
"when the reciprocal of three times a number is subtracted from the reciprocal of the number, the results is one sixth." find the number.
:
Let x = the number - =
Multiply by 6x
6x* - 6x = 6x
cancel the denominators and you have:
6 - 6(3) = x
6 - 18 = x
-12 = x
the number is -12

See if that's true - =
Minus a minus is a plus + =
