Two-Step Equations taught by Zeus

Storyboard Text

  • Hello Students, I am Zeus, and Im here to teach you about two-step equations
  • YAY TWO-STEP EQUATIONS
  • First let's start with the equation 1/2x+8=22, does anyone know the first step
  • 1/2x+8=22
  • no...
  • Ok, well then the first step is to subtract the eight from the 22 and the 8 instead of using it to add
  • 1/2x+8=22
  • -8 -8
  • 1/2x=14
  • 1/2x X 2/1=14/1 X 2/1
  • Next you will want to divide 14 and 1/2x by 1/2 but instead we will use the inverse operation and multiply by 2/1
  • x=28/1
  • -8 -8
  • 1/2x+8=22
  • 1/2x=14
  • 1/2x X 2/1=14/1 X 2/1
  • -8 -8
  • 1/2x+8=22
  • 1/2x=14
  • Finally, we will simplify x=28/1 to x=28
  • x=28
  • x=28/1
  • Thanks Zeus, See you next time
  • And that's all class, I will see you next time, but in History Class
  • 1/2x X 2/1=14/1 X 2/1
  • 1/2x+8=22
  • -8 -8
  • 1/2x=14
  • x=28
  • x=28/1
