№99 (с. 33)
Условие. №99 (с. 33)
скриншот условия
99. Решите систему уравнений:
a) $ \begin{cases} (x + 5y)(x - y) = 7, \\ (x + 5y)(x + y) = 21; \end{cases} $
б) $ \begin{cases} xy(x + y) = 48, \\ xy(x - y) = 16. \end{cases} $
Решение. №99 (с. 33)
Решение 2 (rus). №99 (с. 33)
а)
Дана система уравнений:
$$\begin{cases}(x + 5y)(x - y) = 7 \\(x + 5y)(x + y) = 21\end{cases}$$
Заметим, что в обоих уравнениях есть общий множитель $(x + 5y)$. Поскольку правые части уравнений не равны нулю, то и $(x + 5y) \neq 0$. Это позволяет нам разделить второе уравнение на первое:
$$ \frac{(x + 5y)(x + y)}{(x + 5y)(x - y)} = \frac{21}{7} $$
После сокращения общего множителя $(x + 5y)$ получаем:
$$ \frac{x + y}{x - y} = 3 $$
Из этого уравнения выразим $x$ через $y$:
$x + y = 3(x - y)$
$x + y = 3x - 3y$
$y + 3y = 3x - x$
$4y = 2x$
$x = 2y$
Теперь подставим полученное выражение для $x$ в первое уравнение исходной системы $(x + 5y)(x - y) = 7$:
$(2y + 5y)(2y - y) = 7$
$(7y)(y) = 7$
$7y^2 = 7$
$y^2 = 1$
Отсюда находим два возможных значения для $y$: $y_1 = 1$ и $y_2 = -1$.
Для каждого значения $y$ найдем соответствующее значение $x$:
1. Если $y_1 = 1$, то $x_1 = 2y_1 = 2 \cdot 1 = 2$. Получаем решение $(2; 1)$.
2. Если $y_2 = -1$, то $x_2 = 2y_2 = 2 \cdot (-1) = -2$. Получаем решение $(-2; -1)$.
Ответ: $(2; 1)$, $(-2; -1)$.
б)
Дана система уравнений:
$$\begin{cases}xy(x + y) = 48 \\xy(x - y) = 16\end{cases}$$
В обоих уравнениях присутствует общий множитель $xy$. Так как правые части уравнений не равны нулю, то $xy \neq 0$. Разделим первое уравнение на второе:
$$ \frac{xy(x + y)}{xy(x - y)} = \frac{48}{16} $$
Сократив $xy$, получаем:
$$ \frac{x + y}{x - y} = 3 $$
Как и в предыдущем задании, из этого соотношения следует, что $x = 2y$.
Подставим $x = 2y$ во второе уравнение исходной системы $xy(x - y) = 16$:
$(2y)y(2y - y) = 16$
$2y^2(y) = 16$
$2y^3 = 16$
$y^3 = 8$
Извлекая кубический корень, находим единственное действительное решение для $y$:
$y = \sqrt[3]{8} = 2$
Теперь найдем соответствующее значение $x$:
$x = 2y = 2 \cdot 2 = 4$
Таким образом, решением системы является пара чисел $(4; 2)$.
Ответ: $(4; 2)$.
