Use an elimination strategy to solve this linear system:
10x + 10y = 1030
5x + 5y = 135

MathMate,
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.
