k hiểu chỗ nào vậy bạn

\(\frac{x-1}{34}+\frac{x-5}{10}+\frac{x}{7}-\frac{x-10034}{1111}=0\)

\(\Rightarrow\frac{x-35+34}{34}+\frac{x-35+30}{10}+\frac{x-35+35}{7}-\frac{x-35-9999}{1111}=0\)

\(\Rightarrow\frac{x-35}{34}+1+\frac{x-35}{10}+3+\frac{x-35}{7}+5-\frac{x-35}{1111}-9=0\)

\(\Rightarrow\frac{x-35}{34}+\frac{x-35}{10}+\frac{x-35}{7}-\frac{x-35}{1111}=0+9-1-3-5\)

\(\Rightarrow\left(x-35\right)\left(\frac{1}{34}+\frac{1}{10}+\frac{1}{7}-\frac{1}{1111}\right)=0\)

vì \(\frac{1}{34}+\frac{1}{10}+\frac{1}{7}-\frac{1}{1111}\ne0\Rightarrow x-35=0\Rightarrow x=35\)

vậy x=35

Living in the infinite trajectory of time sometimes we forget its value for the life of each person. Time is a flow, drifting on and on and never coming back. Therefore, the time for each person is extremely valuable, it is true to the adage that "time is gold and silver".

Indeed, time is more precious than gold and silver, because time is infinite and our life is finite. We humans are born, then soon grow up, grow old and die. But time will remain forever, it goes on flowing through life after life and life after another. Not fast, not slow, just gently imprinting on each person's life. Then when, in a moment of life we ​​look back, we will have to say a sentence: "Time passes so fast".

What is time? We only know time is calculated in seconds, minutes, hours, months, years. In the vast space and in the world with many metaphysical things, who has determined the time fully and comprehensively. Time is clearly an abstract concept but its imprint in people's lives every time it passes is clear. Those are the wrinkles on the face when youth goes through, these are changes of life, the continuous development of society over thousands of years. Sometimes when we turn around, we startled to realize that time has taken so many things. Therefore, although we cannot define the exact time, we still know one thing for sure: time is extremely valuable, it carries a lot of meaning for each human being.

There are times when we can do a lot of work in life. It can be said that time is an important condition to create a colorful life for us. For each person, time is life, is money, is knowledge. When we are young, we must cherish the time more than gold and silver to act, turn our dreams and aspirations into reality, create beautiful flowers to offer ... Space is associated with age and the whole human life. Each time period, the people benefit, people will accumulate knowledge and understanding capital; people will bring to their community and give themselves good careers.

Time is so priceless. Yet there are people who do not know how to value time, regardless of the time that goes by and do useless things. Truly precious time, more precious than gold. But it is important to know what is right and useful for everyone and society with the time we have. Do not know how to value time, waste time on useless and futuris things prostitution, drugs, spending the night with alcohol, stimulants, in schools and restaurants , hotels ... that we ruin our own lives, we will make us cruel, maimed and become criminals who cause pain, mourning for others, and are a burden of society.

Time can give us all, youth, love, passion and happiness. But it can take us all. So, while we have time, know how to take advantage of it. Time is a measure for each person to adjust themselves, how to live, how to live so that time passes without wasting, so that whenever we look back, we have no regrets about the time that has passed.

If one fine day you woke up, what would you do ? For me, I would wake up, brush my teeth, do exercise and go to the kitchen to cook breakfast. Do you think after I have finished eating breakfast, I will lie down on a sleeping bed ? I do not do that, I will wash dishes after breakfast and use my free time to learn English online on olm.vn. Sometimes I help my parents do housework. At noon, my family just ate rice and watched TV. In the afternoon, I chat with my friends on Facebook and learn English together. In the evening, my family had dinner and chatted happily, Time to avoid COVID-19 was fun and nice. What about your free time ? Please tell me !!!
