Basic education has always been the most concerned issue for schools and parents, and primary education, as the most important part of basic education, has attracted much attention. mathmatics Com has prepared the steps and methods of enumerating equations to solve application problems, hoping to help you prepare for the review of junior high school and get into key junior high schools!

Steps and methods of solving application problems by mathematical equations in Xiaoshengchu

Significance of solving application problems with 1 series equation

* Use equations to solve application problems and get the unknowns of application problems.

Steps to solve application problems with two equations

* find out the meaning of the problem, determine the unknown, and express it with X;

* Find out the equal relationship between the quantities in the question;

* column equation, solve the equation;

* Check or check, write the answer.

The method of solving application problems with three-column equation

* synthesis method: first, list the known number (quantity) and unknown number (quantity) in the application problem into relevant algebraic expressions, then find out the' equivalent relationship' between them, and then list the equations. This is a thinking process from part to whole, and its thinking direction is from known to unknown.

* Analysis method: first find out the equivalence relation, then list the known number (quantity) and unknown number (quantity) in the application problem into relevant algebraic expressions according to the need of establishing equivalence relation, and then list the equations. This is a thinking process from the whole to the part, and its thinking direction is from unknown to known.

The range of solving application problems by four-column equation

Application of solutions to common equations in primary schools;

A general application questions;

B. sum time and difference time;

C, calculating the perimeter, area and volume of the geometric shape;

D score and percentage application problems;

E ratio and proportional application.

Junior high school entrance examination is an important examination for primary school students to enter key junior high schools. I hope everyone will review carefully. At the same time, I hope that the steps and methods we have prepared to solve the application problems will help everyone in the process of preparing for the senior high school entrance examination!
