    -12x-18=-6x-9-3 (3-2x)

    -12x-18=-6x-9-9+6x

    -12x-18=-6x+6x-9-9

    -12x-18=-18

    -12x-18=-18

    +18=+18

    -12x=0

    X=0

    -12x-18 and - 6x-9-3 (3-2x)

    First, distribute the - 3 into the parentheses. The second expression will turn out as such:

    -6x-9-9-6x.

    From here, you need to combine like terms (variables and numbers). - 12x-18.

    So, yes, these two expressions are equal.
