  1. Chapter 3 All About Equations!

  2. 3.1 and 3.2 Addition and Multiplication Property of Equality

  3. The Addition Property of Equalityif a = b, then a + c = b + c

  4. - 7 - 7 x = -5 Show your work exactly like this: x + 7 = 2 Write the problem: Add same number to both sides of “=“: Write answer with box around it

  5. The weekly rent on an apartment was increased by $82. The new rental cost is $675. What is the previous rent? Let x = the previous rent. x + 82 = 675 - 82 - 82 x = 593

  6. A number is increased by 36 is 15. Find the number. Let x = the original number. x + 36 = 15 - 36 - 36 x = -21

  7. A number decreased by 83 is 46. Find the number. Let x = the original number. x - 83 = 46 +83 +83 x = 129

  8. The Multiplication Property of Equality For all rational numbers a, b , and c Ifa = b, thenac = bc

  9. Solve: 5x = 30 Show your work exactly like this tonight

  10. Solve: -12x = -8

  11. To solve an equation like: Multiply both sides of the equation by the reciprocal of the coefficient

  12. Solve:

  13. Solve:

  14. Kayla bought 12 identical bowling balls. They weighed a total of 90 pounds. How much did each ball weigh? Let b= the weight of one ball
