    Giải thích các bước giải:

    Ta có:

    $\dfrac{x}{-12}=\dfrac{6}{y}=\dfrac{-z}{32}=\dfrac{-75}{-1000}$ 

    $\to\begin{cases} \dfrac{x}{-12}=\dfrac{-75}{-1000}\\ \dfrac{6}{y}=\dfrac{-75}{-1000}\\ \dfrac{-z}{32}=\dfrac{-75}{-1000}\end{cases}$

    $\to\begin{cases}x=-12\cdot \dfrac{-75}{-1000}\\ y=6:\dfrac{-75}{-1000}\\ -z=32\cdot \dfrac{-75}{-1000}\end{cases}$

    $\to\begin{cases}x=-\dfrac9{10}\\ y=80\\ -z=\dfrac{12}5\end{cases}$

    $\to\begin{cases}x=-\dfrac9{10}\\ y=80\\ z=-\dfrac{12}5\end{cases}$
