Помогите с алгеброй ПОЖАЛУЙСТА 9 класс

Гдз в помощь

Блок 1:

• 1а: x = 5, y = 3
• 1б: (x = 3, y = 4) и (x = 4, y = 3)
• 1в: (x = 7, y = 3) и (x = 3, y = 7)
• 1г: (x = 3, y = 2), (x = 3, y = -2), (x = -3, y = 2), (x = -3, y = -2)

Блок 2:

• 2a: x = 4, y = 10
• 2б: (x = 5, y = 3) и (x = -3, y = -5)
• 2в: (x = 5, y = 4) и (x = 4, y = 5)
• 2г: (x = 2√2, y = 3√2), (x = 2√2, y = -3√2), (x = -2√2, y = 3√2), (x = -2√2, y = -3√2)



3a: x = 7, y = -1
3б: (x = 4, y = 2) и (x = -2, y = -4)
3в: (x = 6, y = 4) и (x = 4, y = 6)
3г: (x = 3, y = 6), (x = 3, y = -6), (x = -3, y = 6), (x = -3, y = -6)



4a: x = 38/7, y = 37/7
4б: (x = 5, y = 2) и (x = -2, y = -5)
4в: (x = 6, y = 5) и (x = 5, y = 6)
4г: (x = 2, y = 7), (x = 2, y = -7), (x = -2, y = 7), (x = -2, y = -7)
