through it first, then view the video answers or you can work though it as you view the videos.

  • Step one:  Add or subtract the equations to eliminate one variable.
  • Step two:  Solve the resulting equation for the other variable.
  • Step three: Once you find the value of the one variable, substitute it into one the equations to find the value of the other.
