And Representing the Solution Set on a Number Line Solving Linear Inequalities
Essentially, they are EQUATIONS with INEQUALITY signs • You can solve Inequalities using the same skills • You need to understand the language of Inequality – next slide. • You need to be careful with negative values of the unknown! • Your teacher will explain that one later! What is an INEQUALITY
Inequality Signs LESS than 2 < 5 “2 is less than 5” Or, from the right, “5 is greater than 2” GREATER [or more] than 6 > 3 “6 is greater than 3” Or, from the right , “3 is less than 6” LESS than OR equal to GREATER than OR equal to
