Lesson 6.6.7
Equivalent Expressions
Equivalent Expressions
Objective: To understand how to use
properties to simplify expressions.
Equivalent Expressions
A term can be a single number or variable or
numbers and variables multiplied together
and separated by addition or subtraction.
e.g.
4x + 4
This expression has 2 terms.
Equivalent Expressions
A coefficient is the numerical factor of a term
that contains a variable.
e.g.
4x + 4
In this expression there is only one term that
has a variable and the coefficient is 4.
Equivalent Expressions
A term without a variable is called a constant.
e.g.
4x + 4
Constant.
Equivalent Expressions
Like terms are terms that contain the same
variable. Only like terms can be added or
subtracted.
e.g.
4x + 6 + 5x
Like terms
Equivalent Expressions
To simplify an numeric or algebraic
expression, use properties to write an
equivalent expression that has no like terms
and no parentheses.
Numeric
3 + 3 = 2(3) or 6
Algebraic
x + x = 2x
