92 

\(x+\dfrac{-7}{12}=\dfrac{17}{18}-\dfrac{1}{9}\)

\(x+\dfrac{-7}{12}=\dfrac{5}{6}\)

\(x=\dfrac{5}{6}-\dfrac{\left(-7\right)}{12}\)

\(x=\dfrac{10}{12}+\dfrac{7}{12}=\dfrac{17}{12}\)

93

\(\dfrac{-7}{15}-x=\dfrac{4}{5}+\dfrac{-2}{3}\)

\(\dfrac{-7}{15}-x=\dfrac{2}{15}\)

          \(x=\dfrac{\left(-7\right)}{15}-\dfrac{2}{15}\)

         \(x=-\dfrac{3}{5}\)

94

\(\dfrac{1}{2}-\left(x-\dfrac{5}{11}\right)=\dfrac{-3}{4}\)

         \(x-\dfrac{5}{11}=\dfrac{1}{2}-\dfrac{-3}{4}\)

        \(x-\dfrac{5}{11}=\dfrac{5}{4}\)

       \(x=\dfrac{5}{4}+\dfrac{5}{11}\)

      \(x=\dfrac{75}{44}\)

95

\(\dfrac{3}{4}+\left(\dfrac{2}{5}-x\right)=\dfrac{1}{4}\)

          \(\dfrac{2}{5}-x=\dfrac{1}{4}-\dfrac{3}{4}\)

           \(\dfrac{2}{5}-x=-\dfrac{1}{2}\)

                  \(x=\dfrac{2}{5}-\dfrac{-1}{2}\)

                  \(x=\dfrac{9}{10}\)
