giải phương trình:
|3x - 7| - x = 3

⇒ |3x - 7| = x + 3

điều kiện: x + 3 ≥ 0 ⇒ x ≥ -3

trường hợp 1: 3x - 7 ≥ 0 ⇒ x ≥ 7/3
khi đó |3x - 7| = 3x - 7

thay vào phương trình:
3x - 7 = x + 3
3x - x = 10
2x = 10 ⇒ x = 5
thỏa điều kiện

trường hợp 2: 3x - 7 < 0 ⇒ x < 7/3
khi đó |3x - 7| = 7 - 3x

thay vào phương trình:
7 - 3x = x + 3
7 - 3 = 4x
4 = 4x ⇒ x = 1
thỏa điều kiện

kết luận: x = 1 hoặc x = 5

topic 3:I like online shopping because it’s convenient and saves a lot of time. I can compare prices easily and read reviews before buying. However, sometimes the items look different from the photos. Even so, I still prefer online shopping overall.

topic 2:My favourite place to shop is Muji. The store is clean, simple, and very peaceful. I usually buy stationery and small home items there. The products are good quality, and the staff are helpful. I always feel relaxed whenever I visit the store.

topic 1:I once felt very nervous before giving a short presentation at school. Even though I had prepared, my hands were shaking and my voice was a bit unsteady. I was afraid of making mistakes in front of my classmates. After a few seconds, I took a deep breath and continued speaking slowly. In the end, everything went fine, and I felt relieved.
