3. Standards I Can… Standards for Mathematical Practice
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. Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive
Standards for Mathematical Practice

5. 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.
