Solving Multi-Step Linear Inequalities
Most linear inequalities require more than one step to solve. The process follows the same general strategy used for solving linear equations: apply properties of inequality to simplify both sides, and securely collect all variable terms on one side and all constant terms on the other. A critical difference arises when isolating the variable at the end: if both sides must be multiplied or divided by a negative number to solve, the direction of the inequality sign must be reversed.
