Question 1055518
There are no coordinates (no solution).
If you add both equations, you get
-x-5y+x+5y=8-15 ,
which simplifies to 0=-7.
Obviously there is no ordered pair of values (x,y) that can make 0 equal to -7.
Both variables were eliminated at the same time,
and what was left is not true.
There is no solution.
The two equations represent parallel lines.
