Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

In an equation, you want to get the variable...

• on one side

• to disappear

• by itself

• to sing and dance

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

• multiply

• divide

• add

• subtract

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.
