Ryan tried to solve the system of equations shown below.

{3x-2y=11-1.5x+y=-4He concluded that the system has no solution. Which is the best evaluation of Ryan's conclusion?

A

He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3, which means the system has no solution.

B

He is incorrect. If the second equation is multiplied by 2 and subtracted from the first equation, the result is 6x-4y=19, which has infinitely many solutions.

C

He is correct. For any positive value of x, the corresponding value of y is negative, which means the system has no solution.

D

He is incorrect. Both equations describe lines that have infinitely many solutions.
