    Ask all your questions in one thread, it makes things neater...


    $\displaystyle 4x-5x>3x+2$

    Subtract: $\displaystyle -1x>3x+2$

    Add 1x to both sides: $\displaystyle 0>4x+2$

    Subtract 2 from both sides: $\displaystyle -2>4x$

    Divide both sides by 4: $\displaystyle \frac{-2}{4}>x$

    $\displaystyle

    -2>3x+x
    $
    $\displaystyle

    -2>4x

    $\displaystyle

    \frac{-2}{4}>x

    $\displaystyle

    \frac{-1}{2}>x

    $
    $\displaystyle
    => x<\frac{-1}{2}

    How would this help? The question was asked 9 months ago and you didn't really change anything from what Quick posted?? (Except to add a few steps, which if the original poster didn't understand they would've posted their question by now...)

    You're right. But I must say that the timestamps on these posts are too small to notice on the first glimpse.
