Bitte die Terme eindeutiger senden (ich hoffe, dass es so richtig ist !).
$${\frac{{\mathtt{A}}}{\left({\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}}{\mathtt{\,\times\,}}{\mathtt{b}}{\mathtt{\,\small\textbf+\,}}{\mathtt{c}}{\mathtt{\,\times\,}}{\mathtt{d}} = {\mathtt{0}}$$ richtig so ?
$${\mathtt{A}}{\mathtt{\,-\,}}{\frac{{\mathtt{G}}}{\left({\mathtt{t}}{\mathtt{\,\small\textbf+\,}}{\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}}{\mathtt{\,\times\,}}{\mathtt{b}}{\mathtt{\,\small\textbf+\,}}{\mathtt{c}}{\mathtt{\,\times\,}}{\mathtt{d}} = {\mathtt{0}}$$ richtig so?
1.) $${\frac{{\mathtt{Ab}}}{\left({\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}} = {\mathtt{\,-\,}}{\mathtt{cd}}$$ $${\mathtt{Ab}} = {\mathtt{\,-\,}}\left({\mathtt{cd}}{\mathtt{\,\times\,}}\left({\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)\right)$$ $${\mathtt{\,-\,}}{\frac{{\mathtt{Ab}}}{{\mathtt{cd}}}} = {\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}$$
$${\mathtt{x}} = {\mathtt{p}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{Ab}}}{{\mathtt{cd}}}}$$
2.) $${\mathtt{A}}{\mathtt{\,-\,}}{\frac{{\mathtt{Gb}}}{\left({\mathtt{t}}{\mathtt{\,\small\textbf+\,}}{\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}} = {\mathtt{\,-\,}}{\mathtt{cd}}$$ $${\frac{{\mathtt{Gb}}}{\left({\mathtt{t}}{\mathtt{\,\small\textbf+\,}}{\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}}\right)}} = {\mathtt{A}}{\mathtt{\,\small\textbf+\,}}{\mathtt{cd}}$$ $${\mathtt{t}}{\mathtt{\,\small\textbf+\,}}{\mathtt{p}}{\mathtt{\,-\,}}{\mathtt{x}} = {\frac{{\mathtt{Gb}}}{\left({\mathtt{A}}{\mathtt{\,\small\textbf+\,}}{\mathtt{cd}}\right)}}$$
$${\mathtt{x}} = {\mathtt{t}}{\mathtt{\,\small\textbf+\,}}{\mathtt{p}}{\mathtt{\,-\,}}{\frac{{\mathtt{Gb}}}{\left({\mathtt{A}}{\mathtt{\,\small\textbf+\,}}{\mathtt{cd}}\right)}}$$
Bitte noch einmal überprüfen !
