My favourite subject in school is English. It is quite easy and pleasant to study it. English is used in each field of life and it is useful to know it. The last advantage to know English is I can talk with all people talking English. This holidays when I was in Gdańsk somebody asked all people: ?Do you speak English?? Everybody talked ?No? and ?Nie wiem o co chodzi.?. When she came to me and asked the question ?Do you speak English?? I could say ?Yes, how can I help you?? She told ?How can I get to the bus station?? I told ?Can you see this building? The station is behind it. Please go this way?. She smiled to me and walked away. I was happy that I could help. As you can see English is useful in life. All of us study it in everyday situations and activities. The language is quite simple and logic. I use it all the time. This is why I English and it is my favourite subject in school.

X x 8,01 - X : 100 = 38
X x 8,01 - X x 0,01 = 38
X x (8,01 - 0,01) = 38
X x 8 = 38
X = 38 : 8
X = 4,75
