Intermediate Algebra Review Part 10
In this Intermediate Algebra Review lesson, the instructor goes over how to solve and check absolute value equations. They demonstrate by solving for x in different equations, reminding the viewer to isolate the absolute value by adding or subtracting first. They also explain that the solutions can be checked by plugging in the value for x and making sure both sides of the equation match. The lesson concludes with an example of an impossible equation with no solution.
