Pro která reálná čísla \(a\), \(b\), \(c\), \(d\) platí rovnost?
\[
2 \cdot \left (\array{
a& c\cr
b & d \cr
} \right )
-
\left (\array{
2& 1 \cr
3 & 5 \cr
} \right )
=
\left (\array{
4& 7\cr
-5 & -5\cr
} \right )
\]
\(a=3\), \(b=-1\), \(c=4\), \(d=0\)
\(a=1\), \(b=1\), \(c=4\), \(d=1\)
\(a=3\), \(b=-4\), \(c=4\), \(d=0\)
\(a=3\), \(b=-1\), \(c=4\), \(d=1\)
Fixed Answer:
None
