solve one step equations remember balance the scale
Your Goal

Isolate the variable (get it alone)

Solve One-Step Equations:Remember—Balance the scale

x + 2 = 7

x + 2 = 7

-2 -2

x = 5

Use Inverse Operations to isolate the variable

  • Inverse Operations “undo” one another add/sub; mult/div; square/square root
  • Get the variable alone (isolate the variable)
  • What you do to one side of the equation, you do to the other side
  • Use your knowledge of properties to make it easier to solve the equation!

One Step

  • Format counts!
  • Line-up your equal signs!!!
  • Move down the page!!!

How do youknow which operation to do first?
