    See below in bold.

    Step-by-step explanation:

    (A) 20 - 4x=12 - x+8-3x

    -4x + x + 3x = 12 + 8 - 20

    0 = 0 This is an Identity.

    Infinite solutions.

    B). 5x+4x-3=24+8x

    9x - 8x = 24 + 3

    x = 27. One solution.

    C. 5x+6=2x+6+3x-15

    5x - 2x - 3x = - 15 + 6 - 6

    0 = - 15

    No solution.
