Solve by the elimination method.
5x-15y=2 and 5x-15y =3
Is there a solution of an ordered pair? Are the infinitely many solutions? or is there no solution?
I got that there is no solution.

1. 5x - 15y = 2
2. 5x - 15y = 3

Subtract equation 2 from equation 1.
or
0 = -1
So, you are correct, there is no solution.
