Lesson Summary:

In Solving Linear Equations Part 3, Mr. Perez guides viewers through three different types of linear equations. The first equation involves clearing out fractions, combining like terms, and isolating the variable to find one solution. The second equation has no solution and results in a contradiction, leading to an empty solution set. The final equation has infinite solutions, resulting in a true statement and a solution set of all real numbers. This lesson provides an opportunity for more practice and understanding of linear equations.

Lesson Description:

    This lesson shows you how to solve some even more complicated problems. Make sure you are comfortable with the previous two lessons before you attempt to tackle the problems in this lesson. Fractions are included in this lesson as well as some equations that do not have just one solution but infinitely many solutions or no solutions.
