а+в=445, а-в=223, тогда
а= 445-в, 445-в-в=223,
445-2*в=223
2в=445-223
2в= 222
в=222:2
в=111, тогда а= 445-111=334

Task 1. Read the text and answer the questions below
Hello, I'm Skips, I'm 30 years old and I live in the park. I have to work every day of the week from
Monday to Sunday, but when I finish my work I have a lot of free time. In my free time I like to practice sports.
I personally prefer adventure sports because those are risky. I like parachuting, bungee jumping and rock
climbing. Usually I go rock climbing on Saturday or Sunday aftemoon, I go on my own. I like climbing
mountains if you want to go climbing you need to be very strong. I go bungee jumping on Friday afternoon.
You need to be very brave to jump. Finally, I have to say that my favorite sport is parachuting; I love
parachuting. I always go parachuting on Thursday but, I never go at night, I always go in the morning.
Parachuting is when you jump off a plane with a parachute on your back, you open it during the fall. It feels like
you were flying and I love that feeling. I went once with Mordecai but he got scared and he didn't jump.
Answer the questions according to the text. Write no more than TWO words.
1. What kind of sport does he prefer?
2. When does he go rock climbing?
3. When does he go bungee jumping?
4. What is Skips' favourite sport?
5. Does he go parachuting at nighttime?
6. Who was afraid to jump with a parachute?
