This award-winning series helps students to build confidence in their ability to "do math" and develop the knowledge and skills required to become mathematically literate. Solving equations is one of the primary uses of algebra. This lesson introduces a method for solving relatively simple linear equations of one variable. Starting with simple equations such as 3x = 15 and x + 5 = 11, the student can develop a sense of the purpose of solving equations. Each step adds a bit more complexity to the process. Eventually the student is able to solve equations such as 3(x + 5) - 6x = 11 - 2x + 8. The importance of checking answers using the original equation is emphasized throughout the lesson. Students will learn to solve simple linear equations: A variable term on both sides, where the "like" term must be combined and that involve parentheses.
