Hướng dẫn từ A-Z cách giải bài toán tìm X

Có nhiều phương pháp để tìm ẩn số x dù bạn đang tính số mũ, căn hay chỉ đang nhân chia. Dù bằng cách nào, bạn luôn phải tìm cách đưa ẩn số x về một vế của phương trình để tìm ra giá trị của chúng. Dưới đây là cách thực hiện:

Sử dụng phương trình tuyến tính cơ bản


  1. Viết phép tính ra như sau:
    • 22(x+3) + 9 - 5 = 32


  2. Tính lũy thừa. Hãy nhớ thứ tự các bước: Trong ngoặc, lũy thừa, nhân/chia, cộng/trừ. Bạn không làm phép tính trong ngoặc được vì trong đó chứa ẩn số x nên phải tính lũy thừa trước: 22. 22 = 4
    • 4(x+3) + 9 - 5 = 32


  3. Thực hiện phép tính nhân.[1] Chỉ cần nhân 4 với các số trong ngoặc (x +3). Cách làm như sau:
    • 4x + 12 + 9 - 5 = 32


  4. Thực hiện phép tính cộng và trừ. Chỉ cần cộng hoặc trừ các số còn lại. Cách làm như sau:
    • 4x+21-5 = 32
    • 4x+16 = 32
    • 4x + 16 - 16 = 32 - 16
    • 4x = 16


  5. Tách riêng biến số.[2] Để thực hiện, bạn chỉ cần chia hai vế phương trình cho 4 để tìm x. 4x/4 = x và 16/4 = 4, vậy x = 4.
    • 4x/4 = 16/4
    • x = 4


  6. Kiểm tra lại kết quả.[3] Chỉ cần lắp giá trị x = 4 trở lại phương trình ban đầu để kiểm tra. Cách làm như sau:
    • 22(x+3)+ 9 - 5 = 32
    • 22(4+3)+ 9 - 5 = 32
    • 22(7) + 9 - 5 = 32
    • 4(7) + 9 - 5 = 32
    • 28 + 9 - 5 = 32
    • 37 - 5 = 32
    • 32 = 32

  1. Good post. I learn something new and challenging on websites I stumble upon on a daily basis. It's always interesting to read content from other writers and use something from other sites.
