### One And Two Step Equations

1. 1. Mixed Practice Solving Equations Practice
2. 2. Solve. Check. <ul><li>1a. a + (-5) = 8 </li></ul>+5 +5 a = 13 1b. r - 9 = 13 + 9 + 9 r = 22
3. 3. Solve. Check. <ul><li>1c. y = 5 </li></ul><ul><li>2 </li></ul> • 2 • 2 y = 10 1d. 3m = 9 ÷ 3 ÷3 m = 3
4. 4. Solve. Check. <ul><li>3a. s + 6 = 0 </li></ul> -6 -6 s = -6 3b. z - 6 = -3 + 6 + 6 z = 3
5. 5. Solve. Check. <ul><li>3c. -d = -9 </li></ul><ul><li>3 </li></ul> • -3 •-3 d = 27 3d. -x = 4 ÷-1 ÷-1 x = -4
6. 6. Solve. Check. <ul><li>5a. w - 18 = 27 </li></ul> +18 +18 w = 45 5b. 9m = 12 ÷9 ÷9 m = 12/9 = 4/3
7. 7. Solve. Check. <ul><li>5c. s = 5 </li></ul><ul><li>4 </li></ul> • 4 •4 s = 20 5d. b + 12 = 11 -12 -12 x = -1
8. 8. Solving Two-Step Equations
9. 9. Solve. Check. <ul><li>1a. 3x - 5 = 16 </li></ul> +5 + 5 3x = 21 ÷3 ÷3 x = 7
10. 10. Solve. Check. <ul><li>1b. -14r - 7 = 49 </li></ul> +7 + 7 -14r = 56 ÷-14 ÷-14 r = -4
11. 11. Solve. Check. <ul><li>1c. 25a - 4 = 96 </li></ul> +4 +4 25a = 100 ÷25 ÷25 a = 4
12. 12. Solve. Check. <ul><li>1d. 60y - 7 = 173 </li></ul> +7 +7 60y = 180 ÷60 ÷60 y = 3
13. 13. Solve. Check. <ul><li>3a. 8a - 7 = 65 </li></ul> +7 +7 8a = 72 ÷8 ÷8 a = 9
14. 14. Solve. Check. <ul><li>3b. 23y + 6 = 75 </li></ul> -6 -6 23y = 69 ÷23 ÷23 y = 3
15. 15. Solve. Check. <ul><li>3c. 52x + 4 = -100 </li></ul> -4 -4 52x = -104 ÷52 ÷52 x = -2
16. 16. Solve. Check. <ul><li>3d. -6z + 15 = 3 </li></ul> -15 - 15 -6z = -12 ÷-6 ÷-6 z = 2
