Answer:

C. I & III

Step-by-step explanation:

I simplifies to ...

2(6x +15 -5x) +4 = 40

12x +30 -10x +4 = 40

2x +34 = 40

__

II simplifies to ...

40 = 2(15 -x) +4

40 = 30 -2x +4

40 = -2x +34 . . . . . . not equivalent to I (sign of x-term is different)

__

III simplifies to ...

12x +30 -10x +4 = 40

2x +34 = 40 . . . . . . equivalent to I

___

I & III are equivalent
