Agenda 1)Homework Folders In 2)Warm up 3)Lesson: Solving Equations by Multiplication and Division 4)Homework (if time)

2
Objective The student will be able to: solve equations using multiplication and division.

3
Warm Up Solve each equation. 1.x – 3 = 5 2.y + 9 = = m – 6 4.n – (-1) = 1 5.f + 4 =

4
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

5
1) Solve -5t = t = (-12) = 60 1.Draw the river to separate the equation into 2 sides 2.Divide both sides by -5 3.Simplify 4.Check your answer 60 = 60

6
2) Solve 15 = 6n = n 15 = 6(2.5) 1.Draw the river 2.Divide both sides by 6 3.Simplify 4.Check your answer 15 = 15

7
3) Solve -3v = v = v = v = 43 4.v = 126 Answer Now

8
4) Solve You dont like fractions? Lets get rid of them! Clear the fraction by multiplying both sides of the equation by the denominator.

9
4) Solve 4 · · 4 x = Draw the river 2.Clear the fraction – multiply both sides by 4 3.Simplify 4.Check your answer

10
3 · = 18 · 3 2x = x = 27 1.Draw the river 2.Clear the fraction – multiply both sides by 3 3.Simplify 4.Divide both sides by 2 5.Simplify 6.Check your answer 5) Solve = 18

11
6) Which step clears the fraction in 1.Multiply by 3 2.Multiply by 5 3.Multiply by Multiply by -5 Answer Now

12
7) Solve 1.b = b = b = 14 4.b = 56 Answer Now

13
Homework pg. 94 #11 – 19, 25 – 32, 40, 41, 42, 45, 53
