Algebra - writing mathematical phrases using letters to represent numbers

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

Constant - the integer in an algebraic 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
4) Verify your answer

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

Solving Addition/Subtraction One Step Equations:
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
4. Verify your answer

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

One-step Equations
In order for you to understand the steps, there are a couple of words you need to know.

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

Constant - the integer in an algebraic expression or equation


Rules for Addition/Subtraction :
1.Isolate the variable
2.Cancel using the opposite operation (create a zero pair)
3.Balance on the other side of the equal sign
4.Verify your answer

Example:

Multiplication/Division

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

Expression- Pattern (many answers)
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
