Bot GPT 3.5 The two equations x - 2y = 6 and 3x - 6y = 18 are equivalent since the second equation is obtained by multiplying the first equation by 3.
So, these two equations are dependent or coincident equations. This means that there are infinitely many solutions that satisfy both equations.
In this case, every point on the line given by x - 2y = 6 will also satisfy 3x - 6y = 18.
Therefore, there are infinitely many solutions to this pair of equations.
