Topics in Linear Inequation

1

Basic Concepts and Definitions

  • An inequation is a mathematical statement comparing two expressions using inequality symbols
  • Linear inequations involve variables with degree 1 only
  • The general form is ax + b > 0, ax + b < 0, ax + b ≥ 0, or ax + b ≤ 0 where a ≠ 0
2

Interval Notation and Number Line Representation

  • Open interval (a, b): excludes endpoints a and b, shown with hollow circles
  • Closed interval [a, b]: includes endpoints a and b, shown with filled circles
  • Semi-open intervals (a, b] or [a, b): include one endpoint only
3

Rules for Solving Linear Inequations

  • Addition-Subtraction Rule: Same operation on both sides maintains inequality direction
  • Multiplication-Division by positive number: Inequality direction remains same
  • Multiplication-Division by negative number: Inequality direction reverses
4

Solving Linear Inequations - Step by Step Method

  • Step 1: Simplify both sides by removing brackets and combining like terms
  • Step 2: Move all variable terms to one side and constants to other side
  • Step 3: Apply multiplication/division rule carefully (watch for negative coefficients)
