ГДЗ по математике 6 класс Дорофеев Задание 882

\[\boxed{\mathbf{882\ (882)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)}\ 0,5x + 3 = 9\]

\[0,5x = 9 - 3\]

\[0,5x = 6\]

\[x = 6\ :0,5\]

\[x = 6\ :\frac{1}{2}\]

\[x = 6 \bullet 2\]

\[x = 12.\]

\[Ответ:x = 12.\]

\[\textbf{б)}\frac{1}{3}x - 2 = 0\]

\[\frac{1}{3}x = 0 + 2\]

\[\frac{1}{3}x = 2\]

\[x = 2\ :\frac{1}{3}\]

\[x = 2 \bullet 3\]

\[x = 6.\]

\[Ответ:x = 6.\]
