\(x-\dfrac{7}{6}=\dfrac{3}{2}\left(x-7\right)\Leftrightarrow x-\dfrac{7}{6}=\dfrac{3}{2}x-\dfrac{21}{2}\Leftrightarrow\dfrac{3}{2}x-x=-\dfrac{7}{6}+\dfrac{21}{2}\)
\(\Leftrightarrow\dfrac{1}{2}x=\dfrac{28}{3}\Leftrightarrow x=\dfrac{\dfrac{28}{3}}{\dfrac{1}{2}}=\dfrac{56}{3}\) vậy \(x=\dfrac{56}{3}\)
