\(\Leftrightarrow\dfrac{x}{27}-1+\dfrac{x}{24}-\dfrac{3}{2}+\dfrac{x}{30}=4\)
\(\Leftrightarrow x\left(\dfrac{1}{27}+\dfrac{1}{24}+\dfrac{1}{30}\right)=\dfrac{13}{2}\)
\(\Leftrightarrow x=\dfrac{\dfrac{13}{2}}{\dfrac{1}{27}+\dfrac{1}{24}+\dfrac{1}{30}}\)\(=\dfrac{7020}{121}\)
Vậy pt có tập nghiệm là S=\(\left\{\dfrac{7020}{121}\right\}\).
