\[x + 6y = 50;\ \ \ (2;8) -\]
\[частное\ решение.\]
\[x = 2 + 6n;\ \ \ y = 8 - n;\ \ n \in Z.\]
\[Для\ x:\ \ n \geq 0;\ \ для\ y:\ \ \]
\[n \leq 7 \Longrightarrow n = 0;1;2;3;4;5;6;7.\]
\[n = 0:\]
\[x = 2 + 6 \bullet 0 = 2;\ \ y = 8 - 0 =\]
\[= 8.\]
\[n = 1:\]
\[x = 2 + 6 \bullet 1 = 8;\ \ \ y = 8 - 1 =\]
\[= 7.\]
\[n = 2:\]
\[x = 2 + 6 \bullet 2 = 2 + 12 = 14;\ \ \ \]
\[\ \ y = 8 - 2 = 6.\]
\[n = 3:\]
\[x = 2 + 6 \bullet 3 = 2 + 18 = 20;\ \]
\[\ \ y = 8 - 3 = 5.\]
\[n = 4:\]
\[x = 2 + 6 \bullet 4 = 2 + 24 = 26;\]
\[\ y = 8 - 4 = 4.\]
\[n = 5:\]
\[x = 2 + 6 \bullet 5 = 2 + 30 = 32;\ \]
\[\ y = 8 - 5 = 3.\]
\[n = 6:\]
\[x = 2 + 6 \bullet 6 = 2 + 36 = 38;\ \ \]
\[\ \ y = 8 - 6 = 2.\]
\[n = 7:\]
\[x = 2 + 6 \bullet 7 = 2 + 42 = 44;\ \]
\[\ \ y = 8 - 7 = 1.\]
\[Ответ:x = 2,\ y = 8;\ \ x = 8,\ \]
\[y = 7;\ \ x = 14,\ y = 6;\ \ x = 20,\]
\[\ y = 5;\]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ x = 26,\ y = 4;\ \ \ x = 32,\ \]
\[y = 3;\ x = 38,\ y = 2;\ \ \ x = 44,\]
\[\ y = 1.\]
