### 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

Balance

x = 4

Simplify

x+2 = 4

2+2 = 4
4=4

Verify

Modeling

x = 4

x+2 = 4

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?
