ГДЗ по алгебре 7 класс Мерзляк Задание 41

\[\boxed{\text{41\ (41).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\ 8 \cdot (7x - 3) = - 48 \cdot (3x + 2)\]

\[56x - 24 = - 144x - 96\]

\[56x + 144x = - 96 + 24\]

\[200x = - 72\]

\[x = - \frac{72}{200}\]

\[x = - \frac{36}{100}\]

\[x = - 0,36\]

\[Ответ:\ x = - 0,36.\]

\[2)\ 4,5 \cdot (8x + 20) =\]

\[= 6 \cdot (6x + 15)\]

\[36x + 90 = 36x + 90\]

\[36x - 36x = 90 - 90\]

\[0x = 0\]

\[Ответ:x - любое\ число.\]
