Here is an algebraic euation: 2x+5=13
The first step your going to do is to isolate the variable by canceling
the constant +5 which would look like this
2x+5-5=13-5

Because we've added -5 to the left we need to add -5 to the right to balance
2x+5-5=13-5

Once you have balanced both sides
you will divide both sides by 2 which
look like this

2x = 9
2      2

Then you cancel the twos you left  of with x then you divide
8 and 2 then you get x=4

now you verify by using the original equation

2x+5=13

Then you substitute the value of x which is 4
SO
now
2(4)+5=13
8+5=13
Now, I know that my answer is right because they are balance

Before I start I'd like to wish everyone a HAPPY ADVANCED EASTER!!! I hope you cry.

Two Step Multiplication:
3n+4=19
3n+4-4=19-4
3n= 15
3       3
n=5

Now verify:
3n+4=19
3(5)=4=19
15+4=19
19=19

Two Step Division
x
3 +2= 0
x
3 +2-2= 0-2
(-3)x
-3 = -2 (-3)
x=6

Now verify:
x
-3+2=0
6
-3+2=0
-2+2=0
0=0
Distributive Property:
This is the worst kind of algebra, in my opinion. I'll show yo how to do it in my stratedgy:
4 (m - 3) = 12
m - 3
m - 3
m - 3
m - 3
---------
4m - 12 = 12

Now it's time for the math definitions!!!Because I am not modelling these questions.

Math Definitions
Variable - A letter that represents an unknown number
Constant - A number that does not change at all
Coefficient - The number that is multiplying the variable

Last but not the least, I'm going to give you this link to something good.I don't know if this "link" has to be math related, so here you go. Click the link.

And this one is just for Meyar, you know just how much she loves squirrels (rabid squirrels in particular). :)

## Two Step Multiplying

Two step multiplying is very easy you just need an equation and know the correct steps on how to be successful.

Let's Start of with the Steps for Success
1. Isolate the Variable
2. Remove the constant using a zero pair
3. Balance(what you do to one side you do to the other)
4. Simplify
5. Cancel the Co-efficient (Xor /)
6. Balance
7. Simplify
8.Verify

Next we need and equation. Today our equation will be 2x+4=8
So...

## Two step Divide

Two step dividing is almost the exactly same as two step multiplying...

## Distributive Property

Distributive Property is a little more different than solving equations

### This is  a class video project we made to explain some algebra

Some things in this project is :
what is a variable, Constant, and coefficient

We focus on three questions in two step multiply,  two step division, and distributive property.

Have Fun and we hope you will enjoy the videos ! :D

Part 1
Part 2
Part 3
http://youtu.be/jrt4UkOMavY

Sorry the insert is not working for me

The way we get all the answer  in this video we will tell you down below.

First you have to isolate the variable by using a zero pair to get rid of the constant then use the opposite operation to get the variable by itself.

The hardest is the distributive property That is the one with the brackets. You must get rid of the brackets by making the variable combined with the number outside the brackets and times the number inside the brackets by the one in the outside brackets to start isolating the new equation.

How you can draw one of the questions we will show here

### Matthew B and Miguel P's Unproject

Hey guys, we have done an ALGEBRA SONG. We totally made all the lyrics so you know it's ORIGINAL! Not the tone dudes, no copyright intended dudes and dudets.

Lyrics:

Billionaire: (Travie McCoy & Bruno Mars)

Hey guys I learned something new,

something you should know too.

I learned Algebra in math today.

It was hard but I got through

That means YOU can too.

So listen up so I can teach you!

We Could Happen: (AJ Rafael)

First, we will work on multiplication,
then we move on to division. There are
6 steps tooooh success. For example is 2k+1=2
Go ahead, solve it, I believe in you!
So, the 1st step is to isolate, isolate the variable
toooh have less trouble.

I Won't Give Up: (Jason Mraz)

The second thing we do, is to cancel the constant,
next we balance, then we simplify.
4th we cancel, cancel the coefficient. Get ready
for the next step. We Verify!! So I won't give up on math,
even if my mom gives me a bath! (lolwut?) We still
got a lot to learn, and Harbeck knows all of it.

Payphone: (Maroon 5 & Wiz Khalifa)

The next part is to divide with the variables.
The first step is to isolate, isolate the variable
after you did that what is next? Zero pair
the constant to reduce the mess!

RAANDDOOOM:

And what is the final step??

Whistle (Flo Rida)

You have to verify, verify to let you know,
that you solved the equation and you have
proof to showwwww...

Variable- A letter that represents an unknown number.

Constant- A number that will always stay the same

Coefficient- A number of quantity placed before and multiplying
another quantity.
