{4x+6y=10
{8x+12y=20
Multiply the WHOLE top row by 2 so that you would have 8x and 8x on both rows so that you would be able to subract.
2(4x+6y=10)
8x+12y=20
8x+12y=20
We are now going to SUBTRACT the first row with the bottom row.
This gives us 0=0  so there are Infinitely many solutions!

First Equation: 4x + 6y = 10
Multiply by 2, 
8x + 12y = 20

Now, we can see it is equal to second equation, so the system has infinite solution here.

In short, Your Answer would be Option D

Hope this helps!
