2. One-Step Equations and Inequalities Chapter Six

3. Addition and Subtraction 15 + x = 31 -15 -15 x = 16 n + 9=27 -9 -9 n = 18 d – 11 = 47 + 11 =+11 d =58 r – 8 = 13 +8 +8 r = 21

4. Alright, let ’ s try it!! x + 5 = 19 w – 14 = 89b + 13 = 26 17 + y = 42f + 15 = 45m – 18 = 13

5. Multiplication and Division 5a = 45 5 5 a = 9 2x = 26 2 2 x = 13 n/9 = 4 (9) n/9 = 4(9) n = 36 x/3 = 7 (3) x/3 = 7 (3) x = 21

6. Alright, let ’ s try it!! 10y = 80h/6 = 812a = 60 r/15 = -10-3e = 36w/4 = 19

7. Word Problems 1.There were 7 roses in the vase. Nancy cut some more roses from her flower garden. There are now 15 roses in the vase. How many roses did she cut ? 2. Joan is baking a cake.

8. Solving addition and subtraction inequalities e + 5 < 97 - 5 - 5 e < 92 x – 2 > 12 + 2 +2 x > 14 34 + g > 89 -34 g > 55 f – 12  25 + 12 +12 f  37

9. Last one, let ’ s try it!! h + 12 < 87i – 13 > 3914 + j < 28 k – 939  27m + 29 < 312n – 825  56
