\(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right)\div16\frac{2}{3}=0\)
\(1-\left(\frac{43}{8}+x-\frac{173}{24}\right)\div\frac{50}{3}=0\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)\div\frac{50}{3}=1-0\)
\(\frac{43}{8}+x-\frac{173}{24}=1\times\frac{50}{3}=\frac{50}{3}\)
\(\frac{43}{8}+x=\frac{50}{3}+\frac{173}{24}=\frac{191}{8}\)
\(\Rightarrow x=\frac{191}{8}-\frac{43}{8}=\frac{148}{8}=\frac{37}{2}\)
