Lesson: Solving Equations by Multiplication and Division Homework (if time)

2
**Objective The student will be able to:**

solve equations using multiplication and division.

3
**Warm Up Solve each equation. x – 3 = 5 y + 9 = 7 8 13 = m – 6**

f + 4 = -5 8 -2 19 -9

4
**To get the variable by itself, which number needs to be moved?**

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 = 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 60 = 60

6
**2) Solve 15 = 6n 6 6 2.5 = n 15 = 6(2.5) 15 = 15 Draw “the river”**

6 6 2.5 = n 15 = 6(2.5) Draw “the river” Divide both sides by 6 Simplify Check your answer 15 = 15

7
3) Solve -3v = -129 v = -126 v = -43 v = 43 v = 126 Answer Now

8
**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.

9
**4) Solve 4 · · 4 x = -48 Draw “the river”**

Clear the fraction – multiply both sides by 4 Simplify Check your answer 4 · · 4 x = -48

10
**5) Solve = 18 3 · = 18 · 3 2x = 54 2 2 x = 27 Draw “the river”**

3 · = 18 · 3 2x = 54 x = 27 Draw “the river” Clear the fraction – multiply both sides by 3 Simplify Divide both sides by 2 Check your answer

11
**6) Which step clears the fraction in**

Multiply by 3 Multiply by 5 Multiply by -12 Multiply by -5 Answer Now

12
7) Solve b = -56 b = -14 b = 14 b = 56 Answer Now

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