    Work: Y=3 / (10-x)

    Solve for x

    * (10-x) both sides

    Y (10-x) = 3

    10y-xy=3

    -10y both sides

    -xy=-10y+3

    :-y both sides

    X = (10y-3) / y

    Simplify

    X=10y/y-3/y

    X=10-3/y

    Answer: x=10-3/y

    Check your work: plug in x

    Y=3 / (10 - (10-3/y))

    Simplify

    Y=3 / (10-10+3/y)

    Y=3 / (3/y)

    Y=3*y/3

    Y=y

    The answer is correct
