MCC8.EE.7 Solve linear equations in one variable. a. Give examples of linear
equations in one variable with one solution, infinitely many solutions, or no
solutions. Show which of these possibilities is the case by successively
transforming the given equation into simpler forms, until an equivalent equation
of the form x = a, a = b, or a = a results (where a and b are different numbers). b.

Definition
Linear Equation
An equation that can be written in the form ax + b = c where
a, b, and c are real numbers and a≠0
Integer
A whole number; a number that is not a fraction (can be
negative).
Inverse Operations
Pairs of operations that undo each other, for example,
addition and subtraction and inverse operations and
multiplication and division are inverse operations.
Additive Inverse
Two numbers whose sum is 0 are additive inverses of one
another. Example: ¾ and – ¾ are additive inverses of one
another because ¾ + (- ¾) = 0
Algebraic Expression
A mathematical phrase involving at least one variable.
Expressions can contain numbers and operation symbols.
Independent Practice
• Finish practice problems

Vocabulary Word
Definition
Variable
A letter or symbol used to represent a number.
Coefficient
A numerical or constant quantity placed before and multiplying the
variable in an algebraic expression (e.g., 4 in 4x)
Evaluate
To perform operations to obtain a single number or value
Solution
The value or values of a variable that make an equation a true
statement.
Like Terms
In algebra, like terms are terms that have the same variables and
powers. Only the coefficients of like terms can be different.
