Mathematics · Class 12 · CBSE — Matrices
If \(A = \begin{bmatrix} 3x & y \\ 1 & 2 \end{bmatrix}\), \(B = \begin{bmatrix} -1 & x \\ y & -1 \end{bmatrix}\), and \(AB' = \begin{bmatrix} 0 & 0 \\ 2x-1 & y-2 \end{bmatrix}\), then which of the following is correct?
- \(x = 0\) and \(y = 3\)
- \(x = \frac{1}{3}\) and \(y = 0\)
- \(x = \frac{1}{3}\) and \(y = 3\)
- \(x = 0\) and \(y = \frac{1}{3}\)
Answer
(C) x = 1 3 and y = 3
