Storyboard Text

  • I need help with an equation
  • Sure what is it?
  • It's 6x+12=24
  • Ok, so your first step is to use inverse operations
  • Ok, but I don't understand how to do that.
  • The expression is used as addition, so subtract 12 from both 12 and 24 
  • Ok, but then we have 6x=12
  • That is where you divide both 6x and 12
  • By how much?
  • You have to divide both 6x and 12 by 6 because 6 is accompanied by a variable
  • So my final answer should be x=2?
  • Well, let's check, if we put 2 into the equation, we then have 6(2)=12. The 2 has to be multiplied with 6 which equals 12, so x=2
