Multiplying & Dividing Algebra~ Lesson 6

3
Remember Addition and Subtraction? Kinda the same idea…

4
Except now, we are working with multiplication and division. Remember… They are opposites. So they undo each other.

5
Remember… In Algebra, we have to do a little organizing before we can solve for the right answer.

6
You know, put like things together on the same side of the equation.

7
4x = 24 Imagine a dividing line through the equal sign. Remember…

8
4x = 24 Remember… Letters go on one side and numbers go on the other. L#L#

9
4x = 24 L#L# Notice that it is tied to the X by multiplication. How can you undo multiplication? DIVISION!

10
4x = 24 L#L# 4 The division undoes the multiplication on this side, so the four is cancelled out.

11
4x = 24 L#L# 4 What you do to one side of the equation, you must do to the other.

12
4x = 24 L#L# 4 What you do to one side of the equation, you must do to the other. x = 6

13
Lets try a few… 3m = = 3j 5s = 135 m = 4 13 = j s = 27

14
Now…lets undo division!

15
x = 24 Imagine a dividing line through the equal sign. Remember… 2

16
x = 24 2 Notice that it is tied to the X by division. How can you undo division? MULTIPLICATION! 2

17
x = The division undoes the multiplication on this side, so the four is cancelled out.

18
x = The division undoes the multiplication on this side, so the four is cancelled out.

19
x = The division undoes the multiplication on this side, so the four is cancelled out. x = 48

20
Lets try a few… m = = w 3 m = = w

21
Homework Time!
