k so where do i go from here

from the EEA you just convert it back into congruent form I think

so x is congruent to 25 is congruent to what

bluebrandonBest ResponseYou've already chosen the best response.0
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

bluebrandonBest ResponseYou've already chosen the best response.0
since (25) is some solution for x

ok well I guess I might try asking on here again then

mathTalkBest ResponseYou've already chosen the best response.1
4x(is equivalent to) 5(mod 21) 21  4x5 214*(4)5 Hence 4 is a solution. ??? I am not sure.
