Lesson Summary:

In this lesson, you will learn how to use algebra to define unknown quantities, write an equation, solve it, and check it using one variable. The instructor demonstrates three different methods of solving the same problem, showing that there are often multiple ways to solve a problem. The lesson concludes with an example problem where the sum of two numbers is 2, and the difference between 8 and twice the smaller number is 2 less than 4 times the larger number. The instructor guides you through the steps of solving the problem and checking the solution, emphasizing the importance of defining variables based on the problem's wording.

Lesson Description:
