Inverse Operations: Multiplication and Division

Solving using inverse operations:  $6x\ =\ 42$  

• x = 7

• x = 6

• x = 42

• x = 48

Solve using inverse operations:
 $x\ \div2\ =\ 12$  

• x = 24

• x = 14

• x = 6

• x = 10

What would be the first step to solve this equation using inverse operations?  $10x\ =\ 50$  

• Divide both sides by 10

• Multiply both sides by 10

• Add 10 to both sides

• Subtract 10 to both sides

What would be the first step to solve this equation using inverse operations?  $x\ \div\ 8\ =\ 10$  

• Multiply both sides by 8

• Divide both sides by 8

• Add 8 to both sides

• Subtract 8 to both sides

Solve using inverse operations.
 $\frac{1}{5}x\ =\ 4$  

• x = 20

• x = 1/20

• x = 4/5

• x = 5/4
