I'm not getting this whole special system of equations thing. Please help me understand
Question: Which system has an infinite number of solutions? A: y = 2x  5 and  2 = y  2x. B: x + 2 = y and 4 = 2y  x. C: y + 3 = 2x and 4x = 2y  x. D: 2y + 6 = 4x and  3 = y  2x.

If one equation is a multiple of the other equation, then both equations are the same, thus having infinite solutions.

What do you mean by multiple?

What I mean is, there exists a set of equations such that one of them has been multiplied by a number to disguise the fact that both of them are equal.

Also, terms have been switched around to disguise it even further.

For example, I can take y = 2x + 3 If I multiply that by 3 I get 3y = 6x + 9

I can switch terms around to get 9 = 6x  3y

But no matter how much I manipulate this equation, each line is equivalent to the previous one.

So find the system where such a condition exists.
