\(a,\Rightarrow\dfrac{3}{7}x=\dfrac{1}{3}\Rightarrow x=\dfrac{7}{9}\\ b,\Rightarrow x=\dfrac{-16.15}{20}=-12\\ c,\Rightarrow\left|x-\dfrac{2}{5}\right|=2,25=\dfrac{9}{4}\\ \Rightarrow\left[{}\begin{matrix}x=\dfrac{9}{4}+\dfrac{2}{5}=\dfrac{53}{20}\\x=-\dfrac{9}{4}+\dfrac{2}{5}=-\dfrac{37}{20}\end{matrix}\right.\\ d,\Rightarrow x+\dfrac{1}{2}=-\dfrac{7}{4}\Rightarrow x=-\dfrac{9}{4}\)
I like English the most and I will share with everyone how to study English effectively without getting bored.
1. If we often watch TV every day, we should watch movies in English or read some books or stories to improve our listening and reading skills.
2. Buy an English pack to learn with pronunciation and writing so we can pronounce English correctly and rarely make spelling mistakes
3. Join the dance or singing activities in English at school or at home so that you can both show your own talents and reduce boredom while learning English.
Here are my sharing on the most effective way to learn English without getting bored. I ask the teachers to choose my lesson
English is a popular and important language today. If you have English as a second mother tongue, then great, all success will come to you. But what about the opposite, everything is deadlocked if you are a fresh graduate who needs a job to think logically with English. Here is Hai 's full English experience:
-Learn English vocabulary.(Every day 10 words is enough to break naxo^-^)
-Learn sentence patterns, English structures. (Don't be discouraged)
-Learn to speak English (Sweet Western accent needs to be shown at this time.)
-Learn to chase, imitate native speakers.
-Listen to English music.
-Read English newspapers (Actually, I'm too lazy)
-If you really need an English degree, you should sign up for a reputable course. The real thing to do is you have to be interested in it, passionate about it.
(I'm a person who loves my mother tongue, so I won't use hello much).
Everyone, please refer.
