Answer 1

Сначала давайте рассмотрим систему уравнений:

1. x + y = 3
2. 10x + y = 3

Для решения этой системы уравнений вы можете использовать метод уравнений с двумя переменными, выразив одну из переменных через другую.

Давайте начнем с выражения y из первого уравнения:

1. y = 3 - x

Теперь подставим это значение y во второе уравнение:

10x + (3 - x) = 3

Теперь решим это уравнение:

10x + 3 - x = 3

Сначала выразим x:

9x + 3 = 3

Теперь вычтем 3 с обеих сторон:

9x = 0

Теперь поделим обе стороны на 9:

x = 0

Теперь, когда у нас есть значение x, мы можем найти значение y, используя первое уравнение:

x + y = 3

0 + y = 3

y = 3

Таким образом, решение системы уравнений:

1. x + y = 3
2. 10x + y = 3

является (x, y) = (0, 3).

Ответ: Существует одно решение, и оно равно (0, 3). Ваш предыдущий ответ о том, что решений нет, является неверным.
