As a teen, I often feel stressed. First, I’m under a lot of pressure to do well at school. I have to complete a huge load of schoolwork, projects and study hard for exams. Then, there is also the stress of having a social life and being accepted by my friends.

I have some ways to deal with stress and pressure. To feel better, I try to relax. I listen to music, read a book, or play my favourite computer game. Exercise is also good for reducing stress. I usually go for walks in the park and have recently taken up badminton. It is also important to talk to someone about stress. I often talk to my older sister; she helps me with all the problems I have.

15.x=-3.5                                                                      b)\(\dfrac{x}{17}\)=\(\dfrac{y}{12}\)=\(\dfrac{x-y}{17-12}\)=\(\dfrac{10}{2}\)=5 vậy x=34 và y=24

15.x=-15

x=-15:15

x=-1

a)3.(-6)+5=-13

b)2.(-2)² -3.(-1)+7=18

a) ta có x.y = k hay k =(-2).(-10)=20

b) với x=4 thì y=20:4=5

với x=-2 thì y=20:(-2)=-10
