Hi Lolgirl44
The equation would be 3027 + 9 = 3036
I figured out this answer by subtracting 3036 - 9 which is 3027 so to check back and make sure I was right I added 9 + 3027 and it equaled 3036 so I knew I was 100% true on that so x + 9 = 3036 is really 3027 + 9 = 36 which is true and that would be your answer.
