First, the term shift method is used to solve:
First, we can move 16 in the equation to the right of the equal sign and get 50-x=30- 16. Then, we operate 50 and 30- 16 to get 50-x= 14.
Next, we need to move x from the left of the equal sign to the right of the equal sign, that is, -x= 14-50. Continue the operation and get -x=-36. Finally, we remove the negative sign from the equation and get x=36. So the solution of equation 50-x+ 16=30 is x=36.
Second, merge similar items to solve:
Another way to solve equations is to combine similar terms. First, we can combine 50 and 16 in the equation to get 66, and then rewrite the equation as 66-x=30.
Next, we need to move x from the left of the equal sign to the right of the equal sign, that is, -x=30-66. Continue the operation and get -x=-36. Finally, remove the negative sign from the equation and get x=36. So the solution of equation 50-x+ 16=30 is x=36.
Finally, it should be noted that when solving equations, it is necessary to follow the laws of mathematical operations and make accurate and orderly calculations. By moving terms or merging similar terms, we can get the solution of the equation. But we should pay attention to check whether the solution conforms to the original equation to ensure the correctness of the solution.
In order to get good grades, we must study mathematics in an orderly way. Here are some effective methods and skills to learn mathematics:
1, listen carefully.
If you want to get good grades in math study, you should first pay attention to class and listen carefully to understand what the teacher says. You can write down what the teacher said and review it as the focus of the review.
2. Think independently.
Independent thinking is very important for understanding mathematical formulas. For example, when encountering a new problem, how to start thinking, how to choose the right method to solve the problem, and whether you can get the right answer through independent thinking.
3, more hands-on practice.
In the review, we should not only prepare the relevant theoretical content, but also do a lot of hands-on practice to consolidate the knowledge we have learned. Different problems will have different solutions. Only by organically combining theory with practical application can we truly and effectively consolidate what we have learned.
4. Be diligent in summing up.
When dealing with some problems, we should be diligent in summing up, so that we can quickly get the correct answer by using similar methods in the future. In the final analysis, it is to associate and restore similar situations or similar formulas in the article to general situations to think about problems.
5. Consolidate and test diligently.
In reviewing, don't forget to fully consolidate and test what you have learned before. For what you have learned a few days ago, you can make an ideological evaluation every day, which can not only ensure the early ability, but also ensure the fragmentation from the outside to the inside.
