Ta có 3x( y + 1 ) + y + 1 = 7
3x( y + 1 ) + ( y + 1 ) = 7
( 3x + 1 )( y + 1 ) = 7
Vì x; y nguyên nên 3x + 1 và y + 1 nguyên
Vậy ( 3x + 1 ); ( y + 1 ) ϵ Ư( 7 ) = { 1; -1; 7; -7 }
Lập bảng giá trị
| 3x + 1 | 1 | -1 | -7 | 7 |
| y + 1 | 7 | -7 | -1 | 1 |
| x | 0 | \(\dfrac{-2}{3}\) ( loại ) | \(\dfrac{-8}{3}\) | 2 |
| y | 6 | 0 |
Vậy các cặp số nguyên ( x; y ) cần tìm để 3x( y + 1 ) + y + 1 = 7 là ( 0; 6 ); ( 2; 0 )
