when I did the EEA I got 4(-5) + 21(1) = 1
anonymous
  • anonymous
but then you have to mult by 5
anonymous
  • anonymous
then x=xnot+bn/d

when I multiplied by 5 I got 4(-25) + 21(5) = 5
anonymous
  • anonymous
o ya then xnot is -25
anonymous
  • anonymous
x=-25+21n
anonymous
  • anonymous
your way of writing things is different then how I did it
anonymous
  • anonymous
you have to find all solutions
anonymous
  • anonymous
yeah I got x is congruent to 17 (mod 21)
anonymous
  • anonymous
k so where do i go from here
anonymous
  • anonymous
from the EEA you just convert it back into congruent form I think
anonymous
  • anonymous
so x is congruent to -25 is congruent to what
anonymous
  • anonymous
so 4(-25) congruent to 5 (mod 21) so x congruent to -25 (mod 21/1) is the complete solution and that is equivalent to x congruent to 17 (mod21/1
anonymous
  • anonymous
since (-25) is some solution for x
anonymous
  • anonymous
then you just put it into the Linear Congruence Theorem, V1
anonymous
  • anonymous
to get the complete solution
anonymous
  • anonymous
o crap ok now i see it
anonymous
  • anonymous
I don't know this stuff super well either lol
anonymous
  • anonymous
did you show eea?
anonymous
  • anonymous
yeah I put it in there
anonymous
  • anonymous
but theres no room
anonymous
  • anonymous
the EEA for those were really short so I just wrote it in there tiny
anonymous
  • anonymous
have you done any other problems on the assignment? I'm stuck on 5c lol
anonymous
  • anonymous
only up to 3
anonymous
  • anonymous
ok well I guess I might try asking on here again then
anonymous
  • anonymous
metoo
anonymous
  • anonymous
4x(is equivalent to) 5(mod 21) 21 | 4x-5 21|4*(-4)-5 Hence -4 is a solution. ??? I am not sure.
anonymous
  • anonymous
i dunno
