a) $\dfrac{5}{8}-\left(x+\dfrac{3}{4}\right)=\dfrac{7}{6}$     $-x-\dfrac{3}{4}=\dfrac{13}{24}$    $-x=\dfrac{31}{24}$$\Rightarrow x=\dfrac{-31}{24}$b) $\left(x-\dfrac{3}{4}\right)+\dfrac{3}{2}=\dfrac{11}{3}$    $x-\dfrac{3}{4}=\dfrac{13}{6}$    $x=\dfrac{35}{12}$c) $\left(x+\dfrac{1}{2}\right)-\dfrac{5}{8}=2$    $x+\dfrac{1}{2}=\dfrac{21}{8}$    $x=\dfrac{17}{8}$d) $\dfrac{11}{2}-\left(\dfrac{4}{5}+x\right)=2-\dfrac{1}{3}$    $\dfrac{11}{2}-\left(\dfrac{4}{5}+x\right)=\dfrac{5}{3}$    $-\dfrac{4}{5}-x=\dfrac{-23}{6}$    $-x=\dfrac{-91}{30}$$\Rightarrow x=\dfrac{91}{30}$  Câu trả lời: a) $\dfrac{5}{8}-\left(x+\dfrac{3}{4}\right)=\dfrac{7}{6}$     $-x-\dfrac{3}{4}=\dfrac{13}{24}$    $-x=\dfrac{31}{24}$$\Rightarrow x=\dfrac{-31}{24}$b) $\left(x-\dfrac{3}{4}\right)+\dfrac{3}{2}=\dfrac{11}{3}$    $x-\dfrac{3}{4}=\dfrac{13}{6}$    $x=\dfrac{35}{12}$c) $\left(x+\dfrac{1}{2}\right)-\dfrac{5}{8}=2$    $x+\dfrac{1}{2}=\dfrac{21}{8}$    $x=\dfrac{17}{8}$d) $\dfrac{11}{2}-\left(\dfrac{4}{5}+x\right)=2-\dfrac{1}{3}$    $\dfrac{11}{2}-\left(\dfrac{4}{5}+x\right)=\dfrac{5}{3}$    $-\dfrac{4}{5}-x=\dfrac{-23}{6}$    $-x=\dfrac{-91}{30}$$\Rightarrow x=\dfrac{91}{30}$
