Who can tell me some tips for solving equations in one yuan at a time, and I will give you an extra 200 points to answer some common problems in the exam as promised!

In fact, it is not difficult to solve the equation in one yuan at a time, and I have no skills.

Just pay attention to the common problems.

1. Remove bracket. This situation can be simplified to a very simple formula after removing the brackets.

Example: 2-(1+x)+(1+x+x 2-x 2)

Solution: The original formula = 2-(1+x)+(1+x+x2-x2).

=2- 1-x+ 1+x+x^2-x^2

=2- 1-x+ 1+x

=2

Like this, it is best to remove the brackets in the first three steps to make the teacher look comfortable.

Note: parentheses after the minus sign. All the symbols in it should be changed. You can remove the brackets directly when adding.

2. denominator. This kind of teacher generally doesn't give tricky questions. For example, it is difficult to divide a denominator. This makes the teacher look uncomfortable.

I can't type this example. I can't type the denominator.

This is the same. Remove the denominator in the first two steps.

Note: if all are divided, but there is a single integer, that integer should be multiplied by the same amount.

If you are afraid to write it down, put the two expressions on both sides of the equal sign in brackets. Then you can easily tell them apart.

#. Frequently asked questions:

It is impossible for a general teacher to have a unary equation. The most common is the price increase plan, or the project right, or the tax rate. Not too rare. When it comes to this topic, it must be difficult to have a long speech. In fact, you can list the formulas beside them and substitute the conditions one by one. Then calculate.

Moreover, there are few solutions to the linear equations of one variable. It's usually just a calculation.

If you don't understand anything, you can continue to ask. I'll give you an answer. I'm in grade two now. I understand the mood of senior one. Friendly reminder ~ If I don't study well in Grade One, it will be difficult for Grade Two to keep up.
