    yes

    Step-by-step explanation:

    any number times nine will be greater if you times the same number by three,

    ex:

    9 (5) + 15=60

    3 (5) + 15=30

    9x+15 > 3x+15

    Disagree

    Step-by-step explanation:

    You can solve this problem by doing as follows:

    9x+15=3x+15

    -3x - 3x

    =

    6x+15=15

    -15 - 15

    =

    6x=0

    Although x=0, x=0 is still a solution to the problem.
