  1. BELL WORK Which pair of equations are NOT equivalent?  A.  3(x + 4) = 27 3x + 12 = 27  B.  5x + 10 – 3x = 24 2x = 34 C.  7(x – 3) = 3(x + 1) 4x = 24 D.  9x – 3 + 6x – 5 = 53 15x – 8 = 53

  2. HANDS ON EQUATIONS LESSON 7

  3. ALWAYS REMEMBER… • Your equation must stay balanced. Whatever you do on one side, you must do the same thing on the other. • Start by combining like terms on each side of the equal sign. • Make sure to get all of the variables on one side and all of the constants on the other. • Remember to check your work.

  4. PRACTICE SHEET #7 3x + 2x = 10 x = 2

  5. PRACTICE SHEET #7 Do this on your bell work sheet. 4x + 2x = x + x + 20

  6. PRACTICE SHEET #7 3x + 5 = x + 19 x = 7

  7. PRACTICE SHEET #7 Do this on your bell work sheet. 2(3x + 1) = x + 22

  8. PRACTICE SHEET #7 3x = 21 x = 7

  9. PRACTICE SHEET #7 3x = 14 + x x = 7

  10. PRACTICE SHEET #7 4x + 3 = x + 21 x = 6

  11. PRACTICE SHEET #7 Do this on your bell work sheet. 5 + x + 3x – x = 2x + 9 - x

  12. PRACTICE SHEET #7 2(3x + 1) = 8 x = 1

  13. PRACTICE SHEET #7 2(2x + 2) = x + 10 x = 2

  14. PRACTICE SHEET #7 4x + 2x + 1 = 2x – x + 21 x = 4

  15. PRACTICE SHEET #7 Do this on your bell work sheet. 2(2x + 4) – 2x = x + 18

  16. PRACTICE SHEET #7 3x + x – 2x + 8 = 3x + x x = 4

  17. EXIT SLIP Ms. Grayson bought several cans of vegetables at the store today for a total of $9.00. Each can is normally $0.75, but Mrs. Grayson had a coupon for $0.25 off per can. Which equation can be used to find n, the total number of cans of vegetables that Ms. Grayson got for $9.00? A.  $0.25(n – $0.75) = $9.00 B.  $0.75n – $0.25n = $9.00 C.  $0.25n – $0.75 = $9.00 D.  $0.75(n – $0.25) = $9.00
