If 
then the value of x – y is
(a) – 3
(b) 1
(c) 3
(d) 5
Solution:
If ![x\left[ \begin{matrix} 2 \\ 3 \end{matrix} \right] +y\left[ \begin{matrix} -1 \\ 0 \end{matrix} \right] =\left[ \begin{matrix} 10 \\ 6 \end{matrix} \right]](https://s0.wp.com/latex.php?latex=x%5Cleft%5B+%5Cbegin%7Bmatrix%7D+2+%5C%5C+3+%5Cend%7Bmatrix%7D+%5Cright%5D+%2By%5Cleft%5B+%5Cbegin%7Bmatrix%7D+-1+%5C%5C+0+%5Cend%7Bmatrix%7D+%5Cright%5D+%3D%5Cleft%5B+%5Cbegin%7Bmatrix%7D+10+%5C%5C+6+%5Cend%7Bmatrix%7D+%5Cright%5D+&bg=ffffff&fg=000&s=2&c=20201002)
then the values of x and y are
(a) x = 2, y = 6
(b) x = 2, y = – 6
(c) x = 3, y = – 4
(d) x = 3, y = – 6
