\(1000-\left(x-\frac{1}{2}\right):5=5:4\frac{2}{3}\)
\(1000-5:\frac{14}{3}=\left(x-\frac{1}{2}\right):5\)
\(\frac{13985}{14}=\left(x-\frac{1}{2}\right):5\)
\(x-\frac{1}{2}=\frac{69925}{14}\)
\(x=\frac{34966}{7}\)
\(1000-\left(x-\frac{1}{2}\right):5=5:4\frac{2}{3}\)
\(1000-\left(x-\frac{1}{2}\right):5=\frac{15}{14}\)
\(\left(x-\frac{1}{2}\right):5=1000-\frac{15}{14}\)
\(\left(x-\frac{1}{2}\right):5=\frac{13985}{14}\)
\(\left(x-\frac{1}{2}\right)=\frac{13985}{14}\cdot5\)
\(x-\frac{1}{2}=\frac{69925}{14}\)
\(x=\frac{69925}{14}+\frac{1}{2}\)
\(x=\frac{34966}{7}\)
