Description

"From Calculation to Equation" PPT courseware 4 for linear equations of one variable

Which of the following formulas is an equation?

32x+45y

12x+15y=40

75>20

19x+45=64

x+y-7z=18

X+y<12

Definition: An equation with unknown numbers is called an equation

Example 1: Use a 24cm long wire to form a square. What is the side length of the square?

Solution: Let the side length of the square be X

4X=24

Example 2: The length of a circular track is 400m. How many times can you run along the track for 3000m?

Solution: If you run x times along the track, you can run 3000m.

400x=3000

summary

By reviewing the definition of equation, understand what is a linear equation of one variable, understand the concept of understanding an equation and what is the solution of an equation

Through the understanding of linear equations of one variable, learn how to formulate linear equations of one variable, that is, analyze the quantitative relationships in practical problems, and use the equality relationships among them to list equations
