Solving absolute value equations
Learn how to solve absolute-value equations. For example, solve 2|x-1|=5.
Sal introduces the idea of an absolute value equation, gives a bunch of examples of such equations and solves them, and discusses how the graph of an absolute value equation should look.
Sal solves the equation 8|x+7|+4 = -6|x+7|+6.
Sal solves the equation |3x-9|=0.
Sal solves the equation 4|x+10|+4 = 6|x+10|+10 to find that it has no possible solution.
Solve equations that contain absolute value expressions.
