    A and D

    Step-by-step explanation:

    x+x+x+2=3x+2

    A does work because 3x+2=3x+2 (I think A might've been a typo)

    B doesn't work because the coefficients are switched

    C doesn't work because that's 3x+6

    D does work because that evaluates to 2x+2+x=3x+2

    E doesn't work because it's not 3x+2x
