Let A = \(\left[ {\begin{array}{*{20}{c}} 1&2\\ { - 5}&1 \end{array}} \right]\) and A-1 = xA + yI, then value of x and y are
1
\(x = \frac{{ - 1}}{{11}},y = \frac{2}{{11}}\)
2
\(x = \frac{{ - 1}}{{11}},y = \frac{-2}{{11}}\)
3
\(x = \frac{{ 1}}{{11}},y = \frac{2}{{11}}\)
4
\(x = \frac{{ 1}}{{11}},y = \frac{-2}{{11}}\)
