Description

"Number of Stamps" Using Equations to Solve Problems PPT Courseware 3

Oral arithmetic: state the solution to the equation.

6m=42 4x=20

9y=54 24n=96

3y=45 4y=36

5n=50 4m=100

Quick answer:

2m-m= 4y+3y= x+x=

y+2y= 6m-m= 9n-3n=

y+y= 2b-b= x+4x=

6m-4m= 7y+2y= 9x-4x=

teaching objectives

In this lesson, we will learn to solve some slightly complex equations. Students must master how to use equations to solve practical problems.

(1) Understand the meaning of the question, find the unknown number, and express it with x.

(2) Find the equality between quantities in word problems and formulate equations;

(3) Solve equations;

(4) Check and write the answer.

1. During the Olympic torch relay held in Sanya City, the male and female torchbearers sent by our county ran a total of 2,000 meters during the torch relay. It is known that the distance run by the male torchbearers is four times that of the female torchbearers. How many meters did the male and female torchbearers each run?

Determine whether the statements in the following questions are correct.

(1) a2>2a. ( )

(2) A formula containing unknown numbers is called an equation. ( )

(3)5x+5=5(x+1). ( )

(4) The solution to equation 3x-6=12 is 6. ( )
