5x â‰¡ 4(mod3)
Not sure how I would solve for x.
Do you have any other congruence?
\(5x â‰¡ 4\pmod 3 \implies 3|( 5x-4) \implies x = 5 ,17,\cdots\)
I just started this course, so I'm not yet totally familiar with all the symbols. | means 3 is divisible by (5x-4) doesn't it? I thought that was just a statement. How did you get 5 and 17? Thanks
a|b means a divides b.
or b is divisible by a
and I checked few values of x ...
Is there a way to set up an equation here? We have learned Fermat's little theorem in congruence notation and Wilson's theorem as well. Does it have something to do with those?
I don't think so, if you had multiple congruences then I would suggest Chinese remainder theorem.
Alright, thank you.
Glad to help :)
