Question

(x-2)(2y+3)=26

Answer 1

\(TH1,\left\{{}\begin{matrix}x-2=2\\2y+3=13\end{matrix}\right.\\ =>\left\{{}\begin{matrix}x=4\\y=5\end{matrix}\right.\\ TH2,\left\{{}\begin{matrix}x-2=13\\2y+3=2\end{matrix}\right.\\ =>\left\{{}\begin{matrix}x=15\\y=-\dfrac{1}{2}\end{matrix}\right.\\ TH3,\left\{{}\begin{matrix}x-2=-2\\2y+3=-13\end{matrix}\right.\\ =>\left\{{}\begin{matrix}x=0\\y=-8\end{matrix}\right.\\ Th4,\left\{{}\begin{matrix}x-2=-13\\2y+3=-2\end{matrix}\right.\\ =>\left\{{}\begin{matrix}x=-11\\y=-\dfrac{5}{2}\end{matrix}\right.\)
