    3x + 9 = 861, what is the value of x?

    Yes, it's 284, because 3x=852 so x=284

    Is this about a captcha/forum signup question or did you miss when you aimed for general off topic?

    Otherwise yeah it seems to be a standard rearrange to find x equation.

    Yes, that's correct.

    I see. In that case, it is quite the challenge!

    Never had that before.

    Where dat ass is
    So to work out 'x' (or whatever the unknown value is) you can just pull the numbers to the otherside to it ends up looking like
    Code:
    x = 123
    So if we have 3x + 9 = 861, we can first MINUS 9, because to take 9 off one side, we must do it to the other, so take 9 away from 861
    Now 3x = 852
    So to get ride of x, we divide both sides by 3, so 3x / 3 = x and 852 / 3 = 284
    so now were just left with x = 284, thus its the answer :)

    I would have some nice equations. :evil:

    Seriously, they're quite fun if you know how to solve them basically.
