1. Objective The student will be able to: solve equations using multiplication and division. Designed by Skip Tyler, Varina High School

2. 1) Solve. -5t = 60 To get the variable by itself, which number needs to be moved? -5 -5t means that -5 and t are being multiplied. 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 1.Draw the line to separate the equation into 2 sides 2.Divide both sides by -5 3.Simplify

4. 2) Solve 15 = 6n 6 6 2.5 = n 1.Draw the line 2.Divide both sides by 6 3.Simplify

5. 3) Solve -3v = -129 1.v = -126 2.v = -43 3.v = 43 4.v = 126 Answer Now

6. 4) Solve What number do you need to get rid of to get the x alone? It is being divided. What are you going to do to get rid of the division?

7. 4) Solve 4 · · 4 x = -48 1.Draw the line 2.Multiply both sides by 4 3.Simplify

8. 4) Solve -6 · · -6 x = -60 1.Draw the line 2.Multiply both sides by -6 3.Simplify
