Chapter 8: Algebraic Problem Solving

**Variable **- a variable is a letter used to represent one or more numbers; Example: In the expression 2x+3, the letter "x" is a variable.

**- an equation is a statement that is formed by placing an equals sign between two expressions. Example: The statement 10=2x+3 is an equation**

__Equation__**- An algebraic expression consists of numbers, variables, and operations to be performed. Example: 7p+2.50**

__Algebraic Expression__**- To evaluate an expression is to find the value of an expression by replacing each variable with a given value, and simplifying the result.**

__Evaluate__**- To solve means to find the value of the variable that makes the equation true.**

__Solve__** One-Step Equation** - solving an equation that requires only one operation is called a one-step equation.
