There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 6xy - (6xy + 6{x}^{2} - (3xy + 11{x}^{2})) + 7 - (5xy + 16{x}^{2})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -2yx - 11x^{2} + 7\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -2yx - 11x^{2} + 7\right)}{dx}\\=&-2y - 11*2x + 0\\=&-2y - 22x\\ \end{split}\end{equation} \]
