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

2 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

3 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

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

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

6 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.

7 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

8 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

9 6) Which step clears the fraction in
Multiply by 3 Multiply by 5 Multiply by -12 Multiply by -5 Answer Now

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