Use an elimination strategy to solve this linear system:

10x + 10y = 1030
5x + 5y = 135

  • math - ,

    These two lines are parallel and distinct, hence there are no solutions.

    Show that this is the case by dividing the first one by two to get
    Since both equations have 5x+5y on the left, and different values on the right, it shows that the two lines are parallel and distinct => no solutions.
