Solving Addition/Subtract Inequalities SWBAT solve one step inequalities by applying the Addition and Subtraction Properties of Inequality; graph the solution set of an inequality

Set up the problem Eddie’s little brother has been saving only dollar bills in a piggy bank. On Monday, after he put \$12 in his piggy bank, there was at least \$33 in it. How much money was in Eddie’s little brother’s piggy bank before Monday? Dollars before plus dollars is at total Monday added least x +\$12≥\$33

x + \$12 ≥ \$33 What operation is being done? What is the inverse operation? What is the next step after you have solved an equation? How can you check it?

Examples n + 4 ≤ 10 n + 8 ≥ 14 4 < n – 9 d + (-3) > 2 t + 24 > 36 12 > x + 5

Try the problems on your paper X ≥ -7 -5 > k x < 7 t > 32 732
