elementary number theory - Solving Congruence Equations Bbb Z_11

I have an equation 6(mod11)x=3(mod11)



and I need to find the variable x which solve the equation.
I found that x=6 by trying x=0,1,2,3,4,5.



Before, posing this question, I made a search here and in youtube and found the way which described above: https://www.youtube.com/watch?v=U9Eo6Bsvm4M.



That`s an easy equation but the question is how can I find the variable without try all the options?
