2(m-2n)=2, y=57; (2)y=3-2x代入， 4x+3(3-2x)=11, m-2n=1m-n=6,
-2x=2, x=-1;
2(m-2n)x-6y=6---------(1)X2
2x+(m-n)y=7---------------(2) 2
用加减消元法2(m-2n)-2=2x3-7
①-3+m-n=3+7
②①②化简得：2m-4n=1
④③-④x2得：n=25/2③-④x4得：m=51/2应该没错吧
（2）②*2得4X+2Y=6③①-③的Y=5把Y=5代入③得4X+10=6解得X=-1所以原方程组的解是｛X=-1，Y=5

Criticism (批评) is everywhere in life. It is up to you to decide how to react to it. Learn how to deal with criticism and lead a happier and more relaxing life.Ask yourself how the criticism will affect you. Will you lose your job because of the criticism? Will you lose what is important to you because you are criticized? Will life stop existing if your opinions are not accepted? Surely not! So, don’t worry about it. Instead, remember that some criticism actually helps you make some improvements.You absolutely cannot stop what people say. What you can do, however, is to change the way you react to criticism. If you let it upset you, then the blame is on you. You have the right to decide what to do with the criticism you receive.Don’t be afraid to accept criticism. No one likes to be told that he is wrong. Yet, every single person has, at one time or another, been blamed for something. Realize that it’s normal. You may have received some strong criticism, but it doesn’t mean that you are foolish, or that you don’t have the ability to do something properly. If you are afraid to put your work out for others to see, you’ll& never know if you are a capable person. Try not to think of it in that way and don’t take it seriously. If you can learn to be optimistic, you will remove some stress and nervousness about what people think, thus becoming happier.Consider where the criticism comes from. It may help you step back and examine what causes the criticism. Is the critic just trying to offer constructive criticism? It is much easier to accept correction or guidance from someone that has good intentions. This type of criticism is known as valid criticism, because there is a valid point or reason to it. On the other hand, there are critics that offer their advice just to be negative. This is commonly referred to as invalid criticism because it is often not of any use at all.Do your best. And if someone doesn’t like what you’ve done, so what? It’s either valid criticism or invalid criticism. But you have the power to decide how you will allow it to affect you.Title: How to deal with criticismThe author’s opinion about criticismCriticism is a (n)小题1:&part
of life and it is up to you to decide your reaction to it.Ways of dealing with criticism●Understand the &小题2:&that criticism has on you:1) Some criticism won’t make a difference to you, so

Write on more than three words for each answer.The father of Western philosophyThe word ‘philosophy’ means ‘love of wisdom’. Philosophy can be thought of as a way of looking at the world around us, or of answering the great questions of life, such as ‘Why are we here ?’ and ‘What is truth?’The father of Western philosophy was Socrates. Socrates was from Athens, in Greece. When he was young, he was a brave soldier. Later, he became a teacher, but he taught for free, and earned his salary from being a common worker. Aside from this, we know very little about him. Since he never wrote a book, we also know very little about his philosophy. Yet, Socrates has had a deep influence on Western thought and science.To understand how this can true, we must understand how Socrates taught. Socrates taught by asking questions. Through this, he challenged his students to develop and explain their own arguments. In many cases, his questions made his students aware of their own errors. Many students got embarrassed and even angry when this happened, while others changed their opinions. Socrates’ way of approaching the truth is now called the Socratic Methods. The idea of asking questions until you reach the right answer is the basis of modern philosophy and science.Unfortunately for him, Socrates questioned too much. He always asked challenging questions to everyone he met, upsetting many people in Athens. Finally, some people had had enough of him, so they took him to court for questioning the existence of the Greek’s Gods and for corrupting the young people of Athens. At his trial, he defended himself by asking his judges yet more questions. This just made a bad situation worse. Finally he was put to death by being forced to drink poison. &&&&&&&&&&&&&&&&Through his death, Socrates became the hero of all people who search for the truth.The Father of Western philosophyThe &&小题1:&&of philosophyPhilosophy can be&小题2:&&as a way of looking at the world around us, or of

Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying. &&小题1:&&However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle. Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position. Undo your seatbelt. &&小题2:&&Unbuckle the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call. &&小题3:&&Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.
Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. &&小题4:Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. &&小题5:&&While there is still air in the car, take slow, deep breaths and focus on what you're doing. A．Open the window as soon as you hit the water.B．Surviving a sinking car is not as difficult as you think.C．It takes 60 to 120 seconds for a car to fill up with water usually.D．Such accidents are particularly dangerous to the risk of drowning.E.In conclusion, if you know what to do in the water, you will be safe.F.This is the first thing to attend to, yet it often gets forgotten in the panic.G.But the sooner the window is open, the sooner you can escape directly through it.请帮我解答第三四小题 _百度作业帮
