如何在此等式中找到x: (x + 35)％26 = 21 ％是模数. 答案是x =90. 请指教，因为我的数学能力不足以解决此问题. 我知道有一些一致性计算，但是不知道如何在c#中实现.

How to find x in this equation: (x + 35)%26 = 21 Where % is modulo. The answer is x = 90. Please advise, because my math skills are not enough to solve this problem. I know that there are some congruence computation, but don''t know how to implement it in c#.

推荐答案

(x+35)%26 = x%26 + 35%26 = x%26 + 9 x%26 + 9 = 21 => x%26 = 12 => x = { 0+12, 1*26+12, 2*26+12,...}
