i need help with this question(adsbygoogle = window.adsbygoogle || []).push({});

893x=266(mod 2432) ,= mean congruence

fisrt i find gcd(893,2432)=19

then i need to find u,v for 893u-2432v=19

the u and v i found is -49 and -18

but the answer here in my book is 79 and 29

after calculating, i found that both the answer are correct. my question is how to get 79 and 29?

thanks.
