The last time I traveled abroad was 3 years ago.

My mother was enthusiastic about singing when she was a young girl.

It's 5 years since I last talked to him.

The red dress is the prettiest of the two dresses.

Had she taken an umbrella, she wouldn't have gotten wet.

Lisa asked me when I would come back.

It wasn't necessary for him to keep that letter.

The exercise was too difficult for me to do.

Hôm nay olm.vn sẽ hướng dẫn em giải dạng toán nâng cao, toán tổng hiệu ẩn hiệu, cấu trúc thi hsg, thi chuyên, violympic.

  Bước 1: tìm hiệu

  Bước 2: giải toán tổng hiệu bình thường

  Bước 3 : kết luận

                            Giải

Ta có sơ đồ: 

Theo sơ đồ ta có hiệu hai số là: 2 \(\times\)(3-1) + 2 = 6

Số chẵn bé là: (58 -6): 2 = 26

Số chẵn lớn là: 26 + 6 = 32

Đs..

Thử lại ta có: Tổng hai số 26 + 32 = 58 (ok)

           Giữa chúng có: 27; 29; 31 ( 3 số lẻ ok)

Vậy kết quả đúng.
