Ryan tried to solve the system of equations shown below.
{3xβ2y=11β1.5x+y=β4He 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 6xβ4y=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.
