    Algebraic Fraction

    Hi,
    I would appreciate your help answering the following question.

    If Y = 3x+2/5-x, express x in terms of y.

    Thank you.

    Re: Algebraic Fraction

    Please clarify: do yuo mean  Y = 3x + \frac 2 5 -x (which is what you wrote), or do you mean  Y= \frac {3x+2}{5-x} ? Or perhaps  Y=\frac {3x + 2} 5 - x?

    Or perhaps since you posted your question in the LaTeX help section you're looking for asistance in writing the equation as I did, using LaTeX?

    Re: Algebraic Fraction

    Hi,
    Y = 3X + 2 divided by 5 - x as per the second option in your post.

    Apologies for not using latex. Yes, I would like help, if possible, in using latex. I am using a mac - if that's relevant.
    Thanks for your help.
    Sean.

    The platform you use is irrelevant. LaTeX is a function of the webpage.

    [TEX] \frac{3x+2}{5-x} [/TEX] gives   \frac{3x+2}{5-x} .



    This subforum will help you with the code. Once you begin, you quickly learn the code. If you click on the “go advanced tab” you should see \boxed{\Sigma} on the tool-bar. That gives the [TEX]..[/TEX] wrap. Your LaTeX code goes between them.

    Here are more examples:
    [TEX](5+2\sqrt{6})^{x^2-3}+(5-2\sqrt{6})^{x^2-3} [/TEX] gives  (5+2\sqrt{6})^{x^2-3}+(5-2\sqrt{6})^{x^2-3}

    Re: Algebraic Fraction

    As for your problem, to solve y= (3x+2)/(5- x) for x, start by multiplying both sides by 5- x.
