Definitions:
Variable: A variable is a placeholder for a number we do not know yet.
Coefficient: The coefficient is the number in front of the variable.

Like Terms: Terms that share the same variable.
We combine like terms by adding the coefficient.
Ex: 3x and 5x are like terms and if we combine them we get
