\(2\left(\frac{3}{4}x-1\right)-3y\left(1-\frac{3}{4}x\right)=0\)
\(\Leftrightarrow\)\(2\left(\frac{3}{4}x-1\right)+3y\left(\frac{3}{4}x-1\right)=0\)
\(\Leftrightarrow\)\(\left(\frac{3}{4}x-1\right)\left(2+3y\right)=0\)
\(\Leftrightarrow\)\(\orbr{\begin{cases}\frac{3}{4}x-1=0\\2+3y=0\end{cases}}\)
\(\Leftrightarrow\)\(\orbr{\begin{cases}x=\frac{4}{3}\\y=-\frac{2}{3}\end{cases}}\)
