Which of the following systems of equations has infinitely many solutions?

4x − 7y = 1; 14y = 8x − 3

8x − 3 = 6y; 12y − 6 = 2x

4x − 5y = 13; 10y = 8x − 26

5y = -x − 5; -2x + 15y = 10

The first one

The others are either 1 line or crossing

anonymous · Answer

@Ashley1997  Isn't it the third one? You get infinitely many solutions when it's identity.
4x - 5y = 13
-8x + 10y = -26

8x - 10y = 26
0 = 0

The first one are two parallel lines.

That would be no solution. It asks for infinitely many solutions which is an identity. 0 = 0. Not 0 = 6 or any of those.
