The question says to Express our answer in the original modulus of 777 but I end up with 130mod(259) which is right according to wolfram alpha so how do I convert it to mod 777? I notice that 777=259(3) but I don't think I'm allowed to just multiply the modulus by 3 to make it work. Any ideas?

Post the question.
The question is the first line 6x=3mod777 with the conditions I've stated above. It should be given as "remainder(s) mod 777"

The (s) is the clue here.

There are 3 distinct values modulo 777 that equal 130 modulo 239. You need to supply all of them. (Which should be easy).
