The skills of solving equations are as follows: using the properties of equations to solve equations, simplifying the method of solving equations, and solving equations by the relationship between addition, subtraction, multiplication and division.

Use the properties of the equation to solve the equation: first of all, we use the equation equation to solve the equation, the first thing we need to understand is that the left and right sides of the equation are added or subtracted from the same number at the same time, the solution of the equation will not change, the left and right sides of the equation are multiplied by a number that is not 0 at the same time, the solution of the equation will not change, and the left and right sides of the equation are divided by a number that is not 0 at the same time, and the solution of the equation will not change. It is more convenient to use the properties of such an equation to solve the equation without errors, and finally the equation can be reduced to a relatively simple formula, and the answer can be directly obtained!

Simplifying the equation: For some more complex equations, it is quite critical to simplify the equation formula, so when simplifying, you need to make a simplification of some formulas inside the equation according to the nature of the equation, and finally simplify a two-step equation or a three-step equation into a one-step equation, if you are not too troublesome, you can finally continue to use the properties of the equation to solve the equation, so that you can successfully calculate the answer, and it will not be too difficult, and there will be no other problems. Disintegration is relatively simple.

Addition, subtraction, multiplication and division of the relationship between the parts of the equation: addition, subtraction, multiplication and division as four methods of operation, there will be in the equation, according to the addition, subtraction, multiplication, division of the four aspects of the relationship to solve the equation, in the process of subtraction can use the relationship between the subtraction = difference + subtraction, and multiplication can be solved with a factor = product divided by another factor, where addition and division are the same, but need to be calculated in reverse.

This is a one-dimensional equation.

x 12The value of an unknown that equalizes the left and right sides of the equation is called the solution of the equation. The process of finding the solution of an equation is called solving an equation. An equation that must contain an equation of unknowns is called an equation. An equation doesn't have to be an equation, an equation has to be an equation.

Related Concepts: 1.An equation containing unknowns is called an equation, and it can also be said that an equation containing unknowns is an equation.

2.The value of the unknown that makes the equation true, called the solution of the equation, or the root of the equation.

3.Solving an equation is the process of finding the values of all the unknowns in the equation.

4.An equation must be an equation, and an equation does not have to be an equation. An equation without unknowns is not an equation.

5.Validation: After the equation is generally solved, it needs to be verified. Verification is to substitute the value of the solved unknown into the original equation to see if both sides of the equation are equal. If it is equal, then the value obtained is the solution of the equation.

6.Precautions: Write the word "solution", align the equal sign, and test.

7.The equation relies on the relation of the parts of the equation, and the relation of the parts of addition, subtraction, multiplication and division (addition + addition = sum, sum - one of the additions = another addition, difference + subtraction = subtraction, subtraction - subtraction = difference, subtraction - difference = subtraction, factor factor = product, product of one factor = another factor, dividend divisor = quotient, dividend quotient = divisor, quotient divisor = dividend).
