$\begin{array}{l}
a)2x + 10 = 16\\
\Rightarrow 2x = 16 - 10 = 6\\
\Rightarrow x = 3\\
\text{Vậy}\,x = 3\\
b)x - \dfrac{1}{3} = \dfrac{5}{4}\\
\Rightarrow x = \dfrac{5}{4} + \dfrac{1}{3}\\
\Rightarrow x = \dfrac{{15 + 4}}{{12}}\\
\Rightarrow x = \dfrac{{19}}{{12}}\\
\text{Vậy}\,x = \dfrac{{19}}{{12}}\\
c)\dfrac{3}{4}:x = \dfrac{5}{{12}}\\
\Rightarrow x = \dfrac{3}{4}:\dfrac{5}{{12}}\\
\Rightarrow x = \dfrac{3}{4}.\dfrac{{12}}{5}\\
\Rightarrow x = \dfrac{9}{5}\\
\text{Vậy}\,x = \dfrac{9}{5}\\
d)2x + 3\dfrac{1}{3} = 7\dfrac{1}{3}\\
\Rightarrow 2x = 7\dfrac{1}{3} - 3\dfrac{1}{3}\\
\Rightarrow 2x = 4\dfrac{1}{3} = \dfrac{{13}}{3}\\
\Rightarrow x = \dfrac{{13}}{6}\\
\text{Vậy}\,x = \dfrac{{13}}{6}\\
e)x - \dfrac{1}{2} = \dfrac{3}{4}:\dfrac{3}{2}\\
\Rightarrow x - \dfrac{1}{2} = \dfrac{3}{4}.\dfrac{2}{3} = \dfrac{1}{2}\\
\Rightarrow x = \dfrac{1}{2} + \dfrac{1}{2}\\
\Rightarrow x = 1\\
f)1\dfrac{1}{2}x - \dfrac{1}{2} = \dfrac{3}{4}\\
\Rightarrow \dfrac{3}{2}.x = \dfrac{3}{4} + \dfrac{1}{2}\\
\Rightarrow \dfrac{3}{2}.x = \dfrac{{3 + 2}}{4} = \dfrac{5}{4}\\
\Rightarrow x = \dfrac{5}{4}:\dfrac{3}{2}\\
\Rightarrow x = \dfrac{5}{4}.\dfrac{2}{3} = \dfrac{5}{6}\\
\text{Vậy}\,x = \dfrac{5}{6}\\
g)\left( {\dfrac{2}{{11}} + \dfrac{1}{3}} \right).x = \left( {\dfrac{1}{7} - \dfrac{1}{8}} \right).56\\
\Rightarrow \dfrac{{6 + 11}}{{33}}.x = \dfrac{{8 - 7}}{{56}}.56\\
\Rightarrow \dfrac{{17}}{{33}}.x = 1\\
\Rightarrow x = \dfrac{{33}}{{17}}\\
\text{Vậy}\,x = \dfrac{{33}}{{17}}
\end{array}$
