Giải: hệ phương trình 2x + y = 20, 5x - 5y = 0

📝 Problem

hệ phương trình 2x + y = 20, 5x - 5y = 0

✨Detailed Solution

1

1. 🔍 Hệ phương trình — Nhận dạng: Chúng ta có hệ 2 phương trình, 2 ẩn:

2

2x + 1y$ = 20$

3

5x + -5y$ = 0$

4

🤔 Tại sao là hệ? Vì có 2 ẩn (x, y) và 2 PT — cần cả 2 để tìm nghiệm duy nhất.
