  • A linear inequality is solved by making the variable the subject of the inequality
  • Inequalities describe a relationship between two expressions
  • Manipulating inequalities is similar to manipulating equations
  • Dividing both sides of an inequality by the same number is necessary to solve it
  • Inequalities with multiple signs can be split into separate inequalities
  • Solving an inequality with multiple signs can be difficult, so it is easier to solve each inequality separately
  • The final step is to combine the solutions of the separate inequalities into a single inequality with multiple signs
