There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{((x - 54345)*\frac{2}{5} - (322678 - x)*\frac{1}{10})}{x}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{\frac{270029}{5}}{x} + \frac{1}{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{\frac{270029}{5}}{x} + \frac{1}{2}\right)}{dx}\\=& - \frac{\frac{270029}{5}*-1}{x^{2}} + 0\\=&\frac{270029}{5x^{2}}\\ \end{split}\end{equation} \]
