Re: discrete structures

i started with 271x=1 (mod 1003) ..i knew the gcd(271,1003)=1 and 1 divides into 1, therefor i think there is a solution. and next following an example in my book, i went on to find the inverse so that i could multiple both sides by it and come up with the solution. Right now I am stuck on finding the inverse ..i am trying to use the matrices method...
