\(2\times\left(x-5\right)-17=25\)
\(2\times\left(x-5\right)=25+17\)
\(2\times\left(x-5\right)=42\)
\(x-5=42:2\)
\(x-5=21\)
\(x=21+5\)
\(x=26\)

2 * ( x - 5 ) = 25 + 17
2 * ( x - 5 ) = 42
x - 5 = 42 : 2
x - 5 = 21
x = 21 + 5
x = 26

Everyone has a place to be born, grow up, grow and go away, always remember. That place is home. I also have a place that is always in my heart, this land, my parents, my grandparents, my friends and my childhood full of the most memorable memories. I love my hometown, love the people here boldly.
In my mind, every country has its own characteris that cannot be confused. The same people in the countryside, too, have their own personalities and feelings.
My hometown has immense rice paddies, a long run that I have not gone. My mother told me that this rice field is still far away, so I have never dared to go. In the season of ripe yellow rice, the rice seed makes me feel an endless yellow carpet. There are diligent buffaloes grazing on high and long dykes. There we can lie still and watch the sky with clouds floating, watching the sun set every time the sun comes down the high mountains.
My hometown is still poor, so the roads with concrete are still very few, the most popular are still winding earth roads. The smell of pebbles rising up into the wind kept coming straight into the bridge of the nose, making me feel too familiar, even if I grew up later, it would not be strange.
Everyone in my hometown is hard working, they sell their face to the land to sell to the sun to feed their children. They are simple, gentle and hospitable farmers. They always care about the people around them. I used to hear my mother say that the people in the countryside appreciate the neighbors, not in the city, who knows the house. She said so, she would the simple life in the countryside.
I still to look at my hometown whenever I am calm and when the sun goes down. Because these are two memorable moments that mark the beginning of the day and are about to end one day. It makes each person feel peaceful, not hustle, slow and strangely quiet.
There are many people who go far away saying that no matter where they go, their homeland is the place to look for the most. Because that place has families, parents, childhood. And me too, I always love my homeland so much.

My parents’ hometown is Long An, but I was born and raised up in Ho Chi Minh City. People usually call it Saigon, and it is the biggest city of Vietnam. It has a lot of fascinating buildings and constructions since it is a modern and developing city. What I love about Saigon is that all the new and old things are perfectly harmonized. Behind the skyscrapers are the small alleys which contain a slower lifestyle and traditional values. My friends and I have a lot of places to go in our free time such as Nguyen Hue walking street, Tao Dan Park, Dam Sen Water Park, Suoi Tien theme park, and many other places which tourists usually visit. Besides the view, it can be said that Saigon is one of the food heaven that people should not miss when they come to Vietnam. We can find almost all kind of Vietnamese cuisine here, and we can enjoy featuring foods on floating restaurants on Saigon River. I love Saigon a lot, because both the people and the city itself are nice to me and whoever wants to visit it.
