    Help me understand solving x in denominator (very basic)

    Hi I'm new to the boards and wondering if anyone can help me wrap my head around the steps it takes to solve this basic question, I believe I have it right but I just want to be sure I haven't just stumbled upon a pattern to solve this question.

    1/x+2 = 5

    So you could say 1 = 5(x+2) = 5x + 10
    x = -9/5?
    Is this correct? Since I've found -9 by solving, what number +10 would equal 1?

    Re: Help me understand solving x in denominator (very basic)

    there's something that's not clear for me with 1/x+2 or 1/(x+2)

    I think you're trying to mean:

    \dfrac{1}{x+2}=5 you're solving is correct

    But if you're trying to mean:

    \dfrac{1}{x}+2=5 no
