when you see a symbol like x +x=10
multiple things add up to ten, but its is 5+5=10 because two different  values like 6+4=10 would have to be x+y=10.

# data[].attributes.body
What is a variable . A variable is a place holder for a unknown number. A variable can be anything like a symbol or a letter.

# data[].attributes.body
When ever you see the same symbol repeated more than once in an equation it is representing the same unknown number

# data[].attributes.body
same letters in an equation do not not have different values

# data[].attributes.body
Algebra is a lot like Arithmetic. It represents the element of the unknown.When we don't know the answer to a problem we use a symbol in it's place.

# data[].attributes.body
Whenever you do something on one side you have to do it to the other side too.

# data[].attributes.body
same letters like x it can not be in the same equation. like x + x = 10
the one letters going to equal 2 numbers

# data[].attributes.body
algebra is a lot like arithmetic

# data[].attributes.body
x+3      y-3

# data[].attributes.body
Algebra is arithmetic but you have an unknown number and to solve it you need to figure out what the unknown number is

# data[].attributes.body
Algebra like arithmetic

# data[].attributes.body
you have to balance the equation

# data[].attributes.body
you have to leave the uknown number by itself

# data[].attributes.body
When you are adding or subtracting you need to use an arithmetic rearrange equation

# data[].attributes.body
If a number is being divied by a number to undo that you need to mulitply both sides .

# data[].attributes.body
Algebra is similar to arithmetic but it has one different thing, a variable.

# data[].attributes.body
it's to keep the equation in balance

# data[].attributes.body
when you add or subtract you have to rearrange equations by having the same value as the other side

# data[].attributes.body
whats ever on the left side of the equal sign its the same as the right side.

# data[].attributes.body
algebra is adding, subtracting, multiplying, and dividing with unknown numbers.

# data[].attributes.body
adding and subtracting expressions: x + 4 5 - 2

# data[].attributes.body
multiplying and dividing expressions: 2/x = 2 (2) y = 6

# data[].attributes.body
one side has to be the same on the other side.

# data[].attributes.body
When you are solving an equation you need to leave the variable alone.

# data[].attributes.body
If you need to rearrange (or undo) you need to do the inverse

# data[].attributes.body
Keep it balanced.

# data[].attributes.body
Algebra is the type of math that uses the element of unknown

# data[].attributes.body
You should put the known number first and unknown number second to make it easier

# data[].attributes.body
It should be balanced.
Expressions- M+4 A - 7

# data[].attributes.body
There are expressions like- x/4  4(2)

# data[].attributes.body
You can cancel unknown numbers

# data[].attributes.body
It uses the same method as +&-

# data[].attributes.body
you can find the unknown number

# data[].attributes.body
The unknown number can be represented by any letter, not only X

# data[].attributes.body
when multiplying (2) X/2 2 is not in the middle because it is actually 2/1
