Solving Multiplication and Division One Step Equations

Solve -15x = -60 for x.

• -4

• 4

• 75

• 45

Answer explanation

Undo multiplication with division. Divide by -15 on both sides of the equal sign. A negative divided by a negative is a positive.

Solve -10x = 20 for x.

• -200

• -2

• 2

• 30

Answer explanation

Undo multiplication with division. Divide by -10 on both sides of the equal sign. A positive divided by a negative is a negative.

5x = 20

• x = 4

• x = 16

• x = 80

• x = 25

How do you solve this equation?

• divide by 8 on both sides

• divide by 10 on both sides

• multiply by 8 on both sides

• multiply by 10 on both sides

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

x/7 = 3

• x = 21

• x = 14 

• x = 35 

• x = 28 

What is the inverse operation needed to solve the following problem?
x/3 = 5

• Addition 

• Subtraction

• Multiplication

• Division

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Which equation has w = 8 as the solution?

• 8w= 64

• 16w = 240

• 16 - w = 9

• 4 + w = 10

how would you solve this equation: 9x=153?

• multiply

• divide

• add
