Answer 1

Извините за путаницу в предыдущем ответе. Давайте решим систему уравнений графическим методом более ясно.

У вас есть система уравнений:

1. \(0.5x + y = 2\) 2. \(-2x + 5y = 1\)

Для начала преобразуем уравнения в уравнения функций:

1. \(y = 2 - 0.5x\) 2. \(y = \frac{1 + 2x}{5}\)

Теперь мы можем нарисовать графики этих функций на координатной плоскости и найти точку их пересечения.

1. Для первого уравнения \(y = 2 - 0.5x\):

- Когда \(x = 0\), \(y = 2\) - Когда \(x = 4\), \(y = 0\)

2. Для второго уравнения \(y = \frac{1 + 2x}{5}\):

- Когда \(x = 0\), \(y = 0.2\) - Когда \(x = -3\), \(y = 1\)

Теперь нарисуем графики этих двух функций на координатной плоскости и найдем точку их пересечения:


Точка пересечения графиков находится приблизительно в точке (0.9, 0.6).

Таким образом, решение системы уравнений графическим методом: \(x \approx 0.9\), \(y \approx 0.6\).
