help with equation.

If 1/3 is subtracted from 3 times the reciprocal of a certain number, x, the result is 4. Which of the following equations determines the correct value x?
3/x-1/3=4. 1/3x-1/3=4. 3(-x)-1/3=4. 1/3-3/x=4 . 1/3-3x=4.
Please help. Thanks.

Re: help with equation.

Number: x
The reciprocal of x: 1/x
3 times the reciprocal of x: 3/x
Substract 1/3 from 3/x: 3/x - 1/x which equals 4

Is that clear?

Re: help with equation.

Did you mean 3/x - 1/3 = 4 ?

Agree that is the answer; I think Drake simply made a typo.
