Question

x-[17/2-(-3/7+5/30]=-1/3

 

Answer 1

\(x-\left[\frac{17}{2}-\left(-\frac{3}{7}+\frac{5}{30}\right)\right]=-\frac{1}{3}\)

\(=x-\left[\frac{17}{2}-\left(-\frac{11}{42}\right)\right]=-\frac{1}{3}\)

\(=x-\frac{184}{21}=-\frac{1}{3}\)

\(\Rightarrow x=-\frac{1}{3}+\frac{184}{21}\)

\(\Rightarrow x=\frac{59}{7}\)

Answer 2

\(x-\left[\frac{17}{2}-\left(-\frac{3}{7}+\frac{5}{30}\right)\right]=-\frac{1}{3}\)

\(x-\left[\frac{17}{2}+\frac{3}{7}-\frac{5}{30}\right]=-\frac{1}{3}\)

\(x-\frac{17}{2}-\frac{3}{7}+\frac{5}{30}=-\frac{1}{3}\)

\(x=-\frac{1}{3}+\frac{17}{2}+\frac{3}{7}-\frac{5}{30}\)

\(\frac{59}{7}\)

Answer 3

\(x-\left[\frac{17}{2}-\left(-\frac{3}{7}+\frac{5}{30}\right)\right]=\frac{-1}{3}\)

\(x-\left[\frac{17}{2}+\frac{3}{7}-\frac{1}{6}\right]=\frac{-1}{3}\)

\(x-\frac{184}{21}=\frac{-1}{3}\)

\(x=\frac{-7}{21}+\frac{184}{21}\)

\(x=\frac{177}{21}=\frac{59}{7}\)
