1 3.6 & 3.7 Solving Simple One Step Inequalities < > < >

2 Solving Inequalities by using Addition and Subtraction Treat them the same way as equations x + 3 > –5 –3 x > –8 –9 8 –7 6 5 4 3 2  m – 4 ≥ –2 + 4 m ≥ 2 –

3 Solving Inequalities by Multiplying and Dividing Treat the same as equations Except When you multiply (or divide) both sides of an inequality by a negative number, you must reverse the inequality symbol to make the statement true < a4a < 4 a4a4 –3 > a or a < ≤ –4a ≥ –4a –4 12 –4

4 w – 8 ≥ –3 + 8 w ≥ 5 Give it a try c + 6 ≤ –1 – 6 c ≤ – < a4a < 4 a4a4 b ≥ –5 –9b ≤ 45 ≥ 45 –9 –9b –9
