Solve an inequality using multiplication EXAMPLE 2 < 7< 7 x –6 Write original inequality. Multiply each side by –6. Reverse inequality symbol. x > –42 Simplify. ANSWER The solutions are all real numbers greater than –42. Check by substituting a number greater than –42 in the original inequality. < 7. Graph your solution. x –6 Solve x –6 > –6 –6 7
