Example
Solving and Graphing or
To solve the compound inequality or , start by solving each inequality independently. For the first inequality, add to both sides to get , then multiply by to find . For the second inequality, multiply by to obtain , then subtract to get . The solution to an "or" compound inequality is the union of these two results: or . Since these regions overlap and cover every possible value on the number line, the final solution includes all real numbers. In interval notation, this is written as .
