    Step-by-step explanation:

    3x/x^ 2 - 6x = 1

    3/x - 6x = 1

    Multiply each term by x

    3 - 6x² = x

    6x² + x - 3 = 0

    Using quadratic formula

    X = [-b ± √ (b² - 4ac) ]/2a

    a = 6, b = 1 and c = - 3

    X = [-1 ± √ (1² - 4 (6*-3) ] / (2*6)

    X = [-1 ± √ (1 + 72) ]/12

    X = [-1 ± √73]/12

    X = [-1 ± 8.54]/12

    X = (-1 + 8.54) / 12 or (-1 - 8.54) / 12

    X = 7.54/12 or - 9.54/12

    X = 0.63 or - 0.8
