    X=12

    Step-by-step explanation:

    Distributing 2 over (x-3) on left hand side and 3 over (x-9) on right hand side we get.

    2x-6=9+3x-27

    Subtracting 2x and 9 from both hand sides and adding 27 ok both sides we get

    27-9-6=3x-2x

    12=x

    Hence value of x is 12

    x = 12

    Step-by-step explanation:

    Given

    2 (x - 3) = 9 + 3 (x - 9) ← distribute parenthesis on both sides

    2x - 6 = 9 + 3x - 27, that is

    2x - 6 = 3x - 18 (subtract 3x from both sides)

    - x - 6 = - 18 (add 6 to both sides)

    - x = - 12 (multiply both sides by - 1), thus

    x = 12
