Overview

A linear inequation is a statement that compares two quantities using symbols such as <, ≤, >, and ≥. It is called linear when each variable occurs in first degree only and there is no term involving the product of variables. A linear inequation in one variable can be written in the forms ax+b>0, ax

Key Concepts

An inequation states that one quantity

An inequation states that one quantity is either less than or greater than another quantity. Examples include ax+b>0 and ax²+bx+c>0.

An inequation is linear if each

An inequation is linear if each variable occurs in first degree only and there is no term involving the product of the variables.

A one

A one-variable linear inequation can be written as ax+b>0, ax+b<0, ax+b≥0, or ax+b≤0, where a≠0.

The set from which values

The set from which values of the variable are chosen is called the replacement set.

The set of all solutions

The set of all solutions of an inequation is called the solution set, and it is always a subset of the replacement set.

Learning Objectives

  • Understand the meaning of an inequation and a linear inequation.
  • Identify linear inequations in one variable and distinguish them from equations.
  • Use replacement set and solution set correctly while solving inequations.
  • Apply the rules for adding, subtracting, multiplying, dividing, and shifting terms in inequations.
  • Solve linear inequations for natural numbers, whole numbers, integers, and real numbers.
