Two Step Inequalities Examples Look at an example with just numbers Consider 2 lt 5 This is currently a true statement Now multiply both sides by 1 If you don t reverse the inequality you have 2 lt 5 which is a false statement If you do reverse the inequality you have 2 gt
Example 1 Solve 2x 1 lt 7 2 x 1 lt 7 First we need to isolate the variable term on one side of the inequality Here on the left 1 1 is added to the variable term 2x 2 x The inverse operation of addition is subtraction So subtract 1 1 from both sides 2x 1 1 lt 7 1 2x lt 6 2 x 1 1 lt 7 1 2 x lt 6 Courses on Khan Academy are always 100 free Start practicing and saving your progress now https www khanacademy math cc seventh grade math cc 7th va
