\(x+\dfrac{-7}{12}=\dfrac{17}{18}-\dfrac{1}{9}\)
\(x+\dfrac{-7}{12}=\dfrac{5}{6}\)
\(x=\dfrac{5}{6}-\dfrac{\left(-7\right)}{12}\)
\(x=\dfrac{10}{12}+\dfrac{7}{12}=\dfrac{17}{12}\)
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
\(\dfrac{3}{4}+\left(\dfrac{2}{5}-x\right)=\dfrac{1}{4}\)
\(\dfrac{2}{5}-x=\dfrac{1}{4}-\dfrac{3}{4}\)
\(\dfrac{2}{5}-x=-\dfrac{1}{2}\)
\(x=\dfrac{2}{5}-\dfrac{-1}{2}\)
\(x=\dfrac{9}{10}\)
