Solving 1-Step Equations with Multiplication and Division

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations
• math
• variable
• PEMDAS

What is the inverse operation of multiplication?

• addition
• subtraction
• division
• none of the above

to solve 6m = 12

• Multiply both sides by 6
• Divide both sides by 6
• Add 6 to both sides
• Subtract 6 from both sides

in 3a =12,
I would....

• add 3 to both sides
• subtract 3 from both sides
• divide both sides by 3
• divide just the right by 3

9z = 81 can be solved be doing the 

• inverse operation, which is divide both sides by 9
• inverse operation which is multiply both sides by 9
• duplicate operation which is divide both sides by 9
• fractal operation which is divide both sides by 9

Solve the equation

3x = 27.

• x = 24

• x = 81

• x = 9

4x = 44

• x = 40

• x = 11

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

r/4 = 13

• r = 17
• r = 52
• r = 27
• r = 9
