    linear equations

    Hi,

    I'm stuck at this problem that i'm doing:

    4/5x-1 = -9/10x+4

    How to do this?

    Thanks in advance.

    Re: linear equations

    To solve for x, you are going to need to isolate it; so, put the x-terms on one side of the equation, and put the rest on the other side.

    Re: linear equations

    Is your equation:

    \dfrac{4}{5x-1} = \dfrac{-9}{10x+4} or is it \dfrac{4}{5x}-1 = \dfrac{-9}{10x}+4

    For the first, just cross multiply to get rid of the fractions. For the second one, multiply everything by 10x to get rid of the fractions.
    Thanks from topsquark
