Explanation Result used: Principles for solving inequalities : “For any real numbers a , b and c : The Addition Principle for Inequalities: If a < b is true, then a + c < b + c is true. The Multiplication Principle for Inequalities: a) If a < b and c > 0 are true, then a c < b c is true. b) If a < b and c < 0 are true, then a c > b c is true. (When both sides of the inequality are multiplied by a negative number, the inequality sign must be reversed.)” Similar statements hold for a ≤ b ”. Calculation: The given inequality is 2 x − 20 < − 0.8 or 2 x − 20 > 0.8 . Compute the solution set of the inequality 2 x − 20 < − 0.8 or 2 x − 20 > 0.8 as below. 2 x − 20 < − 0.8 or 2 x − 20 > 0.8 2 x − 20 + 20 < − 0.8 + 20 or 2 x − 20 + 20 > 0.8 + 20 ( Add 20 on all terms ) 2 x 2 < 19.2 2 or 2 x 2 > 20.8 2 ( Divide 2 on all terms ) x < 9
