Hey guys, I was wondering if someone could give me a hand finding the inverse of a matrix Modulo 26. The matrix is as follows:(adsbygoogle = window.adsbygoogle || []).push({});

4 9 15

15 17 6

24 0 17

I am trying to get a 1 in the first slot, so I know that 4 can't go into 27 evenly to do that. I tried switching the first and the third row, then adding 1/5 of the second row to it to get 27 which = 1 mod 26, but this will get very messy very fast. Just wondering if this is the only way, or am I overlooking a more simplistic method?
