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
    5x+5y=515
    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.
