Example: Solving Absolute Value Equations Requiring Isolation
When an absolute value equation contains extra terms, apply algebraic properties to completely isolate the absolute value expression before splitting it into two equations. For example, to solve , first subtract from both sides to obtain . Next, divide by to yield the isolated equation . Then, formulate the equivalent equations: or . Solving each produces or . Finally, substituting both values back into the initial equation verifies that both and are valid solutions.
