Storyboard Text

  • Once you've done this, you should have x+3+10.
  • Well, first you would want to use RAE to get rid of the subtraction.
  • Mrs. Young, how would you solve x-(-3)=10?
  • You KFC. This means to keep the (x), flip the (-), and change the (3) to a (-3).
  • Why is it x+3=10? Why do you change the -3 and the subtraction symbol?
  • Therefore, you must subtract 3 from both sides because of the equality property of subtraction.
  • So with x+3=10, you would need to do inverse operations. This means to subtract 3 from both side to get the variable by itself.
  • What would you do next?
  • You have to subtract x+3 by 3 which gives you x and then subtract 10 by 3 which gives you 7, so you answer would be x=7.
  • So what would your final answer be?
