我们可以设甲为x，乙为y。根据题意可得： x - y ≡ 20 (mod 4) y - 4 ≡ x / 4 (mod 4) 从第一个等式中，我们可以得到： x ≡ y + 20 (mod 4) 将其代入第二个等式中，得到： y - 4 ≡ (y + 20) / 4 (mod 4) 化简得： y - 4 ≡ (y/4 + 5) (mod 4) y - y/4 ≡ 1 (mod 4) 化简继续得： 3y/4 ≡ 1 (mod 4) 3y ≡ 4 (mod 4) 3y ≡ 0 (mod 4) 因为3和4互质，所以根据同余方程的性质，我们可以得到： y ≡ 0 (mod 4) 因此，y只可能是4的倍数。考虑到余数等于20，所以y只能是20，所以 y = 20 将y = 20代入第一个等式中，得到： x - 20 ≡ 20 (mod 4) x ≡ 40 (mod 4) x ≡ 0 (mod 4) 同理，x只可能是4的倍数。考虑到余数等于20，所以x只能是20，所以 x = 20 因此，甲为20，乙为20。
