    1- I do not see any s !
    2- If you mean x, Clearly, there is no any real number will satisfy it. Do you know why?

    This cannot be solved for x, as it is impossible to have a fraction equal to 0 unless the numerator is equal to 0, which in this scenario it is not.

    Think of it this way:
    If \frac{1}{x}=0
    if you times both sides by x:
    1=0
    This is not possible!

    Edit: Sorry General, I had started to post before you had finished posting.

    I guess an easy way to think about it is, what number can you divide 3 by to give you zero?
