\(3x+7=y\left(x-3\right)\)
\(\Rightarrow3x+7=xy-3y\)
\(3x-xy+3y=-7\)
\(x\left(3-y\right)+3y=-7\)
\(\Rightarrow-x.\left(y-3\right)+3y=-7\)
\(-x\left(y-3\right)+3y-9=-7-9=-16\)
\(-x\left(y-3\right)+3\left(y-3\right)=-16\)
\(\left(3-x\right)\left(y-3\right)=-16\)
\(\Rightarrow3-x;y-3\inƯ\left(-16\right)=\left\{-16;-8;-4;-2;-1;1;2;4;8;16\right\}\)
