Ta có :   \(3n-1⋮n-1\)

\(\Leftrightarrow3n-3+2⋮n-1\)

\(\Leftrightarrow3.\left(n-1\right)+2⋮n-1\)

\(\Leftrightarrow2⋮n-1\)

\(\Leftrightarrow n-1\inƯ\left(2\right)\)

Mà \(Ư\left(2\right)=\left\{1;-1;2;-2\right\}\)

\(\Rightarrow n-1\in\left\{1;-1;2;-2\right\}\)

\(\Rightarrow n\in\left\{2;0;3;-1\right\}\)

Vậy \(n\in\left\{2;0;3;-1\right\}\)

Chúc bạn học giỏi !!! Tham khảo cách của mk nha !!! 

3n-1 chia het cho n-1

Ta có :

S_ABG= 2/3 S_ABD vì AG = 2/3 AD, chung chiều cao hạ từ B

S_ABD= 1/2 S_ABC vì BD = 1/2 BC, chung chiều cao hạ từ A

=> S_ABG= 2/3 x 1/2 = 1/3 S_ABC

S_AGC= S_ABG vì  chung đáy AG, chiều cao BD = DC=> S_AGC = 1/3 S_ABC

S_BGC = 1- 1/3-1/3 = 1/3 S_ABC

_=> S_ABG=S_ACG=S_BGC
