In this video, I do a combination of sections 2.1 and 2.2 to solve linear equations. Many more examples of solving linear equation are shown including equations involving fractions. For the equation involving fractions, we show how to get rid of fractions by multiplying both sides of the equation by the LCM of the denominators.
After that, we discuss identities and contradictions, showing linear equations that have infinitely many solutions and no real solution.
