Làm mẫu câu a bài 1. vì các câu còn lại tương tự
n+7 chia hết cho n-5
\(\Rightarrow\left(n+7\right)-\left(n-5\right)⋮n-5\)
\(\Rightarrow12⋮n-5\)
\(\Rightarrow n-5\inƯ\left(12\right)=\left\{\pm1;\pm2;\pm3;\pm4;\pm6;\pm12\right\}\)
ta có bảng :
| n-5 | 1 | -1 | 2 | -2 | 3 | -3 | 4 | -4 | 6 | -6 | 12 | -12 |
| n | 6 | 4 | 7 | 3 | 8 | 2 | 9 | 1 | 11 | -1 | 17 | -7 |
vậy \(n\in\left\{6;4;7;3;8;2;9;1;11;-1;17;-7\right\}\)
2. làm mẫu câu a:
(2a+3)(b-3)=-12
=>(2a+3);(b-3)\(\inƯ\left(12\right)=\left\{\pm1;\pm2;\pm3;\pm4;\pm6;\pm12\right\}\)
TH1:
2a+3=1 ;b-3=-12
2a=-2 =>b=-9
=>a=-1
