Storyboard Text

  • I hear you need to learn how to solve two-step equations.
  • Yeah! Can you help me?
  • First, you need to look at the equation. For example, you have x-(-3)=10. You need to find the value of x. You need to change the problem to addition so it will be easier to solve. If you change the subtraction sign to addition, you need to change the negative 3 to a positive 3. Now, you have x+3=10.
  • Sure I can! Let's get started.
  • The next step is to isolate the variable. You need to get x alone, and in order to do this you have to subtract 3 from both sides. You do this because you need to use the inverse of subtraction to take away the 3. You need to subtract 3 from the other side to make the equations equal.
  • You should be solving x+3-3=10-3. x-3+3 is x, and 10-3 is 7, so you have x=7. Therfore, x is equivalent to 7. And you're done! It's as simple as that.
  • Thank you!
