2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 168 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Linear Inequalities after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Inequalities use <, >, ≤, or ≥.
  • An inequality is different from an equation because it does not use =.
  • Linear inequalities may involve one variable or two variables.
  • 30x < 200 is not an equation.
  • The solution depends on the domain: natural numbers, integers, or real numbers.
  • Trial and error can be used first, but algebra gives the full solution efficiently.
  • 40x + 20y ≤ 120 is a slack inequality.
  • 40x + 20y = 120 is an equation.
  • The variable x stands for registers and y stands for pens.

Common Mistakes to Avoid

An inequality can be solved exactly like an equation, and the inequality sign behaves the same way as the equal sign.

The inequality sign reverses whenever any operation is done, including addition or subtraction.

30x < 200 has one answer only, or x can be any real number because it is a simple inequality.
