Meyar's Unproject13, the Most Awesome Blog Post You've ever Seen

Get ready for the most horrible awesome blog post you've ever seen...









Modeling and solving one step equations

Multiplication

Solving

3x= -12
Isolate the variable

3x= -12
__     __
 3       3   

Balance

x= -4

Verify

3x= -12
3(-4) = -12 
 -12 = -12

 Modeling











x = -4

Verify 
3x= -12
3(-4) = -12 
 -12 = -12

Division

 Solving

  r = 7

__    

 2    

Isolate the variable

 (2) r = 7(2)
__    
 2    
Balance

r= 14 

Verify
r= 7
_   

14 = 7
__
 2
7 = 7

 









 Now go Kaboom.











Modeling and Solving Two Step Equations 

Multiplication

Solving 

Cancel the constant

4v+3 =19
4v=3-3 = 19-3 
 4v =16

Balance

4v =16

Simplify

Cancel the coefficient

4v =16
__   __
 4    4

Balance

v = 4

Simplify

4v+3=19     
4(4)+3=19
16+3=19
19 = 19

Verify

 

 

 

 

 

 

I bet you didn't know penguins could fly...
 
Modeling   

    












4v =16


          


  








 4v+3=19  
4(4)+3=19
16+3=19
19 = 19

Verify 
















Are you getting bored? Here, have a rabid fox.


Division

Solving


x+2 = 4

_
2

Cancel the constant 

x+2-2 = 4-2
_
2

Balance 

x = 2
-
2

Simplify 

Cancel the coefficient 




(2)x = 2(2)

-

2

Balance 

x = 4

Simplify 



x+2 = 4

_

2

(4) +2 = 4
_
2

2+2 = 4
4=4

Verify 


Modeling  



















x = 4


x+2 = 4

_

2

(4) +2 = 4
_
2

2+2 = 4
4=4

Verify 

Distributive Property

 Solving

3(x-5) =-6
 3 (x) = 3x

3x5= 15  

3x - 15 = 6

3x - 15 + 15 = 6 + 15

3x = 21

3x = 21
__   __
 3     3

x = 7

Verify

3x - 15 = 6

3(7) - 15 = 6

21 - 15 = 6

6=6




















i deserve extra marks for the pictures by the way.....

have you given them to me yet?
oh you have?
