I need help in solving this question. The equation is:
The question is to:
determine all the solutions in Z(17) and in Z(20).
[In Z(17): 9 and 14, in Z(20): none ]
The Z(17) is suppose to be the whole numbers symbol with subscript 17 but i don't know how to do it in Latex. The same applies to Z(20).
Thanks for your help.
