Mathematics

Answer:

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
