    Rational Function

    Solve

    1) $\displaystyle 1/x-1 + 1/x = 5$

    2) $\displaystyle 3x/x^3+x = 5$

    3) $\displaystyle 4x/x-1 = 6$


    It will be appreciated if you explained by steps, so I can write it on my notes. I really need help with this, please help!

    Thank you

    $\displaystyle 4x/x-1 = 6$

    This would imply

    $\displaystyle 4-1 = 6$

    which makes no sense.


    Did you mean?

    $\displaystyle \frac{4x}{x-1} = 6$

    if so

    Spoiler:

    $\displaystyle 4x = 6(x-1)$

    $\displaystyle 4x = 6x-6$

    $\displaystyle -2x = -6$

    $\displaystyle x = 3$
