Which argument correctly determines the number of solutions for 3x - 2y = 8 and 6x - 4y = 10?
A
The system has infinitely many solutions because the second left side is twice the first left side.
B
Multiplying the first equation by 2 gives 6x - 4y = 16, not 10, so the lines are parallel and have no solution.
C
The system has one solution because both equations contain x and y.
D
The system has no solution because neither equation is in slope-intercept form.
