  1. Warm ups - PEMDAS

  2. 3-2 Solving Equations with Multiplication and Division Objective: To solve equations using multiplication and division

  3. 5x= 15 5 5 x = 3 -4r = -28 Examples 1 – 3 (watch & listen) 3w = -11 3 3 w = -11 3

  4. Examples 4 – 6 (do with me)

  5. Example 7 (with a partner)

  6. Six times a number is -96. Find the number. 6n = -96 6 6 n = -16 Negative twelve times a number is -156. Find the number. Examples 8 - 9

  7. TOO (Try on your own) 1) -3x = -24 2) 3)

  8. Homework Pg. 153 # 15 – 31 odd Check your answers in the back of the book.

  9. ObjectiveThe student will be able to: solve equations using multiplication and division.

  10. 1) Solve. -5t = 60 To get the variable by itself, which number needs to be moved? -5 To move the -5, you have to do the opposite operation. What operation will we use? division

  11. 1) Solve -5t = 60 -5 -5 t = -12 -5(-12) = 60 • Draw “the river” to separate the equation into 2 sides • Divide both sides by -5 • Simplify • Check your answer

  12. 4) Solve You don’t like fractions? Let’s get rid of them!  “Clear the fraction” by multiplying both sides of the equation by the denominator.

  13. 4) Solve • Draw “the river” • Clear the fraction – multiply both sides by 4 • Simplify • Check your answer 4 ·· 4 x = -48

  14. Math Lab • Homework • Please finish worksheets from yesterday • Why did the ant run across the cracker box? • What did the Spanish Farmer say to his chicken?

  15. Try these on your own...
