### Demvry's Algebra Post

Algebra - writing mathematical phrases using letters to represent numbers

Variable
- the unknown
- use a letter to represent a number

Constant - the integer in an algeb
raic expression or equation

Solving One-Step Equation
1) Isolate the variable
2) Cancel using the opposite

- Create a zero pair for the CONSTANT
3) Balance on the other side of the equal sign

Ex. n + 6 = 14

Solving One-Step Equation Video

Solving Two-Step Equation
1) Isolate the variable
2) Cancel the constant
3) Balance
4) Simplify the variable
5) Balance
6) Verify

Ex. 2x + 4 = 10

### Kaecee's Algebra Post

Variable: The unknown, using a letter to represent the number.
Constant: The integer in an algebraic expression or equation.
*You have to make a zero pair
Algebra: Writing mathematical phrases using letters to represent numbers
Eg. 9x -7 = -7

1. Isolate the variable
2. Cancel using the opposite
- Create a zero pair for the constant
3. Balance on the other side of the equal sign

3 + p = 8
3 - 3 + p = 8 - 3
p = 5
3 + p = 5
3 + 5 = 8
8 = 8

x - 7 = 13
x - 7 + 7 = 13 + 7
x= 20
x - 7 = 13
20 - 7 = 13
13 = 13

Solving Addition/Subtraction One Step Equations Using Algebraic Tiles:
1. Isolate the variable
2. Cancel the constant using a zero pair
3. Balance
4. Verify

Solving Two Step Equations:
1. Isolate the variable
2. Cancel the constant
3. Balance
4. Simplify the variable
5. Balance
6. Verify

3x + 8 = 11
3x + 8 - 8 = 11 - 8
3x = 9
3x/ 3 = 3/3
x = 1
3x + 8 = 11
3 (1) + 8 = 11
3 + 8 = 11
11 = 11

Variable: The unknown, using a letter to represent the number.
eg. 15 + b = 23
Constant: The integer in an algebraic expression or equation.
eg. n + 16 = 9
You have to make a zero pair for the constant to cancel it out
Algebra: Writing mathematical phrases using letters to represent numbers
eg. n - 8 = -10

1. Isolate the variable
2. Cancel using the opposite
- Create a zero pair for the constant
3. Balance on the other side of the equal sign

Solving Addition/Subtraction One Step Equations Using Algebraic Tiles:
1. Isolate the variable
2. Cancel the constant using a zero pair
3. Balance
4. Verify

Subtraction:

Solving Two Step Equations:
1. Isolate the variable
2. Cancel the constant
3. Balance
4. Simplify the variable
5. Balance

### Tonie's Algebra Post

Algebra

Algebra- Writing mathematical phrases using letters to represent numbers
eg. n+3 = 143x = 18

Variable- a letter that represents a number in an equation or expression
eg. n+11=20 (can be n, x, p, z, or any letter)

Constant- the integer in an algebraic expression or equation
eg. 18+n =35

eg. 5n

Equation- Only has one answer and an equal (=) sign
eg. 5n=20

Algebra Tiles

Isolate the variable
Cancel the constant using zero pair
Balance (do the same thing to the other side)
Verify to check
