    simple Agebra

    Hi, Am working my way through some algebra problems and am quite stumped in my attempt to simplfy at this point!

    ((9/x)= 5/(x-3)) = (x(9/x))=(x(5/(x-3))

    = (9 = 5x/(x-3))

    NB; x= 6+ 3/4.

    Hello, nnjond!

    Solve for x: . \frac{9}{x}\;=\;\frac{5}{x-3}

    Multiply both sides by the LCD, x(x-3)\!:\;\;{\color{blue}x(x-3)}\cdot\frac{9}{x} \;=\;{\color{blue}x(x-3)}\cdot\frac{5}{x-3}

    . . And we have: . 9(x-3) \;=\;5x

    Got it?
