Подставим - 4, вместо «х». Но нужно учесть, что результат в модуле всегда положительный.

|5 ⋅ (- 4) + 8| - 8 ⋅ (- 4) =

= |- 20 + 8| - (- 32) =

= |- 12| + 32 =

= 12 + 32 = 44

Read about Joanna's problem and write a letter to give her some advice.
Прочитайте о проблеме и дайте советы. Например: If I were you, I'd just get my sports kit and go to the lessons.

I've never been really slim, so when I started school I was worried about PE. We did badminton and volleyball, which were OK, but I still felt self-conscious. At first I didn't like putting on my sports kit in front of the other girls in the changing room, but after a few weeks it was OK.
Then we started gymnastics. I really hated it and my teacher, Miss Bell, made it worse.
Last week one by one my classmates jumped over the horse. Then it was my turn. It was really high and I was scared. I couldn't move. Miss Bell laughed at me and joked, "Hurry up, Fatty!" It was terrible. I ran out of the gym.
My face was red and I was crying. I don't know what to do about PE now.
