Уравнения левой таблицы:

1. \[\frac{1}{2}y = 3x + 4\]

   Умножаем обе части на 2:

   \[y = 6x + 8\]

2. \[\frac{1}{3}y = 2x - 5\]

   Умножаем обе части на 3:

   \[y = 6x - 15\]

3. \[\frac{1}{4}y = x + 3\]

   Умножаем обе части на 4:

   \[y = 4x + 12\]

4. \[\frac{1}{5}y = 2x + 1\]

   Умножаем обе части на 5:

   \[y = 10x + 5\]

5. \[\frac{1}{3}y = x + 2\]

   Умножаем обе части на 3:

   \[y = 3x + 6\]

6. \[\frac{2}{3}y = 4x + 6\]

   Умножаем обе части на 3:

   \[2y = 12x + 18\]

   Делим обе части на 2:

   \[y = 6x + 9\]

7. \[\frac{3}{4}y = 6x - 3\]

   Умножаем обе части на 4:

   \[3y = 24x - 12\]

   Делим обе части на 3:

   \[y = 8x - 4\]

8. \[\frac{1}{4}y = -x + 3\]

   Умножаем обе части на 4:

   \[y = -4x + 12\]
