Để n - 6 chia hết cho n - 1 <=> ( n - 1 ) - 5 chia hết cho n - 1

Vì n - 1 chia hết cho n - 1.Để ( n - 1 ) - 5 chia hết cho n - 1

<=> 5 chia hết cho n - 1 => n - 1 là ước của 5

        Ư(5) = { - 5; -1; 1; 5 }

Ta có n - 1 = - 5 => n = - 4 (TM)

         n - 1 = - 1 => n = 0 (TM)

         n - 1 = 1 => n = 2 (TM)

         n - 1 = 5 => n = 6 (TM)

Vậy n = { - 4; 0; 2; 6 }
