Read the following sections: "Define Linear Equations in One Variable" and "Solutions to Linear Equations in One Variable." Then, scroll down to "Exercises," and complete exercises 1-5. Click on the "Show Solution" link for each problem to check your answer.

An important point to take away from this reading is that *equation* is defined as a statement (containing a variable), which may or may not be true, depending on the value of the variable. To *solve* an equation means to find all the values of the variable for which the statement is true. In the following subunits, you will focus on finding these values.
