For the system $\begin{bmatrix}2&-3\\-4&6\end{bmatrix}\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}5\\-10\end{bmatrix}$ which of the following statements are correct? (A) The system has no solution. Choose the correct answer from the options given below: |
(B) and (D) only (A), (B) and (C) only (A) and (D) only (B) and (C) only |
(B) and (C) only |
The correct answer is Option (4) → (B) and (C) only Solution of the system: $2x-3y=5$ $-4x+6y=-10$ Second equation is $-2$ times the first equation. So both equations represent the same line. Hence the system is consistent and has infinitely many solutions. final answer: $\text{(B) and (C)}$ |
