Ok em nhé
TK:
Gọi số cần tìm là \(\overline{ab}\)
a x b : 3 = a + 1
a x b = (a + 1) x 3
a x b = a x 3 + 3
a x b - a x 3 = 3
a x (b - 3) = 3
Vì 3 = 1 x 3 = 3 x 1 nên có 2 TH sau:
TH1: a = 1 và b - 3 = 3 => a = 1 và b = 6 => \(\overline{ab}\) =16
TH2: a = 3 và b - 3 = 1 => a = 3 và b = 4 => \(\overline{ab}\) =34
Đ/S: 16 và 34
I do lots of things in my free time. Sometimes I play computer games or do some outdoor activities. I love playing football and badminton too. I also love socialising with my friends and learning new interesting hobbies on the internet. My sister likes doing DIY. She also enjoys making crafts and collecting little small things, like bracelets or rings. If I have too much homework, I always try to finish it as quickly as possible so I can have time to do what I love. On Sundays, I love eating out with my family. But I really detest onions because of their smell, so I usually order dishes without them.
