    x = 1/216

    Step-by-step explanation:

    Simplify the equation, like the powers.

    81x + 1 = 729x - 2

    Subtract 729x on both sides to balance the equation.

    -648x + 1 = - 2

    Then subtract 1 from both sides.

    -648x = - 3

    Finally divide by - 648, which then leaves x equal to 1/216

    x = 1/216

    1/216

    Step-by-step explanation:

    Move variables to one side and constants to the other

    9^3x-9^2x=3

    factor out 9^2x

    (9^2x) (8) = 3

    9^2x=3/8

    3^4x=3/8

    3^3x=1/8

    x=1/8 x 27

    x=1/216
