\(2\overrightarrow{BA}-\overrightarrow{BE}=3\overrightarrow{AB}\Leftrightarrow\overrightarrow{EB}=5\overrightarrow{AB}\)
Gọi \(E\left(x;y\right)\)
\(\Rightarrow\left\{{}\begin{matrix}\overrightarrow{AB}=\left(-2;3\right)\\\overrightarrow{EB}=\left(-1-x;5-y\right)\end{matrix}\right.\)
\(\overrightarrow{EB}=5\overrightarrow{AB}\Rightarrow\left\{{}\begin{matrix}-1-x=-10\\5-y=15\end{matrix}\right.\)
\(\Rightarrow E\left(9;-10\right)\)
