Answer 1

К сожалению, я не могу визуализировать графики или вставить фотографии. Однако, я могу объяснить, как построить графики и решить систему уравнений графическим способом на основе вашего описания.

У вас есть система уравнений:

1. 3x + y = 5
2. y - 3x = 2

Чтобы построить графики, вам нужно выразить каждое уравнение относительно переменных x и y.

Для первого уравнения: 3x + y = 5 y = 5 - 3x

Для второго уравнения: y - 3x = 2 y = 2 + 3x

Теперь у вас есть две формулы для графиков:

1. y = 5 - 3x (синий график)
2. y = 2 + 3x (зеленый график)

Чтобы построить графики, выберите несколько значений для переменной x, подставьте их в уравнения и найдите соответствующие значения y. Затем постройте точки на координатной плоскости и соедините их линиями, чтобы получить графики.

По описанию точек, которые вы дали:

• Для синего графика: (x=0, y=5), (x=2, y=-1)
• Для зеленого графика: (x=0, y=2), (x=-1, y=-1)

Точка пересечения графиков (то есть решение системы уравнений) будет являться решением задачи. По вашему описанию, точка пересечения равна (x=0.5, y=3.5).

Итак, решение системы уравнений графическим способом: (x=0.5, y=3.5).
