Algebra- Writing mathematical phrases using letters to represent numbers.
ex.
___+3=5,
5-___=2

Solving an Algebraic Equation:

1. Isolate the variable
2. Cancel the constant using zero pair
3. Balance- doing it to both sides
4. verify to check

Variable- a letter that represents a number in an algebraic equation or expression















Constant- the integer in an algebraic equation or expression














Expression-pattern- many answers













Equation- only has one answer and has an equal sign =














One-Step Equations
























Two-Step Equations

Algebra- One-Step Equations

Algebra- writing mathematical phrase using letters to represent numbers

eg.
- __+3=5
- 2πr=c
- πr^2=A
- s^2=A
- 5-___=2
- πd=c
- l x w=A
- l x w x h=v

Steps:
-Isolate the variable
-Cancel the constant using zero pairs
-Balance- do it to the other side
-Verify check
